[C.R.E.A.M.]

Yeah I'm not going to use one of the cliché answers. But what do you guys think of some light hearted humor thrown into an inteview (that's used sparingly, and not overdone, obviously)? I was thinking of doing something like this:

Interviewer: so what would you say are your weaknesses?
Me: Hmm, I have to go with chocolate. Definitely chocolate. <I'll laugh a little bit here>. Ok ok, I suppose you want to know something relevant to my past work experience. In all seriousness...[and then I talk about my actual weaknesses]

I know it's kind of cheesy, but I was thinking it might get the interviewer to laugh a little bit and shows that I'm comfortable dealing with people. I was also thinking it might make the interviewer more comfortable with me, like we're having a conversation between friends, rather than some high stress job interview.
