Helmet!

U: Why don't you ever wear a helmet?

Me: Hmmm... you won't... if on the first day... a fly gets inside it when you are in the middle of traffic!

Puzzle

U: I have a puzzle for you :) Tell me a vehicle which does not have a horn!

Me: Hmm ... (thinking) May be a Concord!

Recursion!

U: Hey, Can you explain me what recursion is?

Me: Try answering these questions... How do you think? How do you think you think? How do you think you think you think?

U: Oooooo... my head is aching...

Me: Yes, that is recursion!

Chicken Pox and Back Pain

U: Hey, you have backpain? Doc told me it is one of the outcomes of chicken pox...

Me: Oh is it? May be... when you get blisters on diagonal points on your back!

Chicken Pox

U: Why the hell is the doc not calling me? Doesn't he know that the more I stand here, the more they will risk the spreading of the disease?

Me: Umm... may be... that is what they want!
