PJ Puram!

I was having a completely arbit conversation with Shrik last night and it was one of those 'rare' occassions when both of us had completely lost all sense of logic. We were cracking the unfunniest jokes and yet laughing like Russel Peters was performing on stage. My jokes are of course unmentionable, but here is a tough one from Shrik.

What would you call a cylinder with radius 'z' and height 'a'?

For the uninitiated (those who don't hang around with people like Shrik), check your 12th std text! Go figure...

P.S: Thanks for making me laugh all the time Shrikant! What would I do without you?
