One of the most popular and easiest to do. Maintain a consistently flat tone for most of his quotes, with a Texan accent.

• "My name is Hank Hill, and I provide the people of this game with propane, and propane accessories."
  
• "Dang it Bobby, standup is hard work. Like selling propane."

Another easy and fun one. Use a tense voice with a slow and umimpressed tone to do this impersonation which is more about improvisation than direct quotes.

• "I'm Mr. Mackey; your substitute comedian mmkay. And I'm here, to make sure we all have fun."
  
• "Booing is mean, mmkay. So don't boo our next guest, player2, mmkay kids..."

I feel like this one takes a lot of energy. Tense your throat and talk almost out the side of your mouth, using a theatrical and often sarcastic voice. If you can nail the laugh then you'll always have something to fall back on. Peter has a slightly low pitched voice, but uses a range that reaches higher pitches at times.

• "How's it going guys, my name's Peter - Peter Griffin."
  
• "Oh boy, this is even worse than that time I did stand-up comedy."

Rick always seems to talk in a tense and pained voice, with his speech complimented by the occasional burp.

• "I turned myself into a pickle. I'm Pickle Rick!"
  
• "Wubba lubba dub-dub! That's my catch-phrase!"
  
• "I told you this place sucks, Morty."

Purse your lips and invoke a breath-heavy Texan accent, keeping a calm, upbeat, and sometimes cheeky demeanor, which goes higher in pitch to add emphasis. Be sure to start every other line with "wow..."

• "Hey, wow. This place is great."
  
• "I'm Owen Wilson and I heard this crazy joke the other day."
  
• "This is unbelieveable. Honestly, you guys are out of control."

Curl your tongue upwards and use a very tense raspy voice, pushing your lower jaw out slightly and limiting your mouth movement while talking in a slow and heavily theatrical tone. He sounds like he's in constant pain but is at peace with that fact. His quotes can easily suit interacting with other players, and is why I wear a mask in Comedy Night.

• "Perhaps he's wondering why someone would shoot a man, before letting them die on stage."
  
• "Crashing this club with no survivors."
  
• "Ah yes, mic spam. Distracting to the uninitiated..."
  
• "Your punishment must be more severe."

The cadence can be as hard to get right as the accent, as he goes through a sentence but stops to give effect in the delivery of an opinion, in an accent which sounds New York but isn't as thick as a New Yorker stereotype. Purse your lips but don't shy away from speaking with a wide mouth, curling your lower lip especially. A good Trump impression can be hilarious, so help invoking his character by scowling your face slightly and talk with your hands as you go through his quotes.

• "This is big-league standup. Everybody knows it."
  
• "We've got the best comedians here, don't we folks?"
  
• "We're going to make - comedy - great - again."
  
• "And this guy booing me? He's low energy people. He's a tremendous dummy. You're fired."

As his character always seems to be trying to get back in control of a situation; speak in a slightly slow commanding voice with a tense throat, and make sure your inner-Arnold is always coming through in a low pitch. Add a hint of anger when putting emphasis on a line rather than raising the pitch, and make sure you're adding breath to the words. Before doing an impersonation; consider re-watching some of his lines on YouTube to stay close to his Austrian accent. As most of his popular quotes are one-liners, it might be difficult to use them to interact with other players.

• "Put dat cookie down!"
  
• "I'm a cop you idiot. I'm detective John Kimble."
  
• "Get to-da choppah!"
  
• "I'll be back..."

Use a fairly nasal voice in an east London accent which gets angrier and louder the longer you speak. Don't confuse the English accent with sounding posh, as he doesn't enunciate his words like a an upper-class gentleman would.

• "My name is my cocaine. Oi, are you listenin'?"
  
• "You're only supposed to blow the bloody doors off!"

What I think makes a Christopher Walken impersonation difficult is his unique cadence. Practice speaking in a thick New York accent, with a nasally and slightly high pitched voice, taking, pauses. In your speech. And adding emphasis where you wouldn't, expect it. The impression, is difficult, but not, impossible.

• "You know, it's cray-zee, when you hear a good Walken, impression, in a place, like this."
  
• "And just as quickly, as I arrive. I, disappear."
