What would you do if...?

I majorly love this game since I was kid, and I didn't see it anywhere (I may be mistaken) but I hope it's not and everyone has fun.

Here's an example of to play:

p1: What would you do if you saw bigfoot?
p2: Run, of course.
What would you do if internet died forever?
p3: Go crazy.
What would you do if...

Good enough?
Good!

Okay, so I've got first question:

What would you do if you met your favorite celebrity?
