(CNN) - John McCain is known to tell a joke from time to time, but how will the Arizona senator stand up next to comedian Steve Carell?
McCain is slated to appear on Saturday Night Live this weekend, during which Carell will play host, a McCain aide confirms to CNN.
The aide says the presumptive Republican presidential nominee will head to New York Saturday to rehearse for his role, though it remains unclear exactly what part he will play.
McCain hosted the comedy sketch show himself in 2002.
Democrats Barack Obama and Hillary Clinton have also made appearances on the show this year.
ummm, grampa, give it up. the youth vote goes to obama and clinton, NOT you!
he wasnt funny on jon stewart either!
how will he ever stay awake for it?
Oh oh...that would probably be a disaster.
This guy is NOT funny, he is scary.
Is he still awake at that time of night?
I think McCain should go on the Golden Girls'
She would be a better VP the Hillary.....
Remind me.....Who cares, again?
Well McCain, I'll vote for you if the sexist pigs get the weakest link Obama in as nominee with the dirty way they've played politics. You will win and Hillary will spend 4 years pointing as you illustrate why you should never have been elected.
HILLARY 08 OR 12 FO SHO
What is he going to do? A paradoy of himself? Can't imagine him being funny. I must congratulate SNL for their Hillary skit last weekend. That was sooo funny and soo true! You nailed her!
Now that should be funny!
Why is this at the top of the ticker?
Here comes the Pandering Express!
McCain will not get my vote. Bush can tell a better joke than McCain and I hate Bush.
I have more wit in my toe nail clippings than McCain does in a life time.
Do you think its worth making her VP and wasting that spot! do you want to see Clinton walking aroung near white house again !!!
Isn't SNL past his bed time?
Well, SNL ripped Clinton apart. Can't wait to see what they do w/McCain. Why on earth do they set themselves up for this? What cost free air time?
He (McCain) has a good sense of humor and can stand up to a good roasting by anybody, any day.
Unlike Obama, if you said anything jokingly negative about him a gang of his supporters will come flying out of the woodwork and from under the rocks, accuse you of racism and rip you to shreds.
We will need a president who can be challenged in the coming years. It should be either Clinton or McCain and not a Jr. Senator who can't be questioned about anything, anytime or anywhere.
JOHN MCCAIN PROMISED HIS MEDICAL RECORDS THIS MONTH, WHERE ARE THEY?
SNL must be desperate for material. How boring, I see John McCain and I want to go to sleep. That poor guy does not even have a pep in his step. I think I will watch a re-run of anything else.
Lorne Michaels for VP!!!!!!!!
Tina Fey Secretary of State!!!!!!!!
Do they have a teleprompter for him?.. I"m sure in his monitone voice that he'll try to say something funny....He's an old man in a young man's game, he'll appeal to those over 70, but they'll be in bed before SNL is on.
Yawn. What a pathetic feeble attempt to seduce the young voters. Nice try McCaine... you'll be laughed AT... not "WITH".
Really? This is news? You can't tell me that the Obama and McCain camps haven't at least exchanged some useful tit for tat on a point of disagreement today.
Seriously – could the mainstream media MAYBE give us some info about the candidates positions, or just ANYTHING that might be useful to uninformed voters? Or do we all really just have to read about McCain going on SNL.
McClinton working it on SNL.
Shame on YOU HILLARY for DISENFRANCHISING voters from the following caucus states:
You DID NOT win the popular vote, even with Michigan and Florida. Don't spread these lies.
I think he should take it easy before he risks a heart-attack..
Let's face it: this is not an old man's job...
