An oldie but a goodie

One of my old students from RMIT just sent me an email about how many advertising people it takes to change a light bulb.

I've seen these gags a dozen times before, but they still make me smile. Here's a couple of my favourites:

Q. How many copywriters does it take to change a light bulb?
A. I’m not changing a bloody thing!

Q. How many art directors does it take to change a light bulb?
A. Does it have to be a light bulb?

Q. How many account executives does it take to change a light bulb?
A. How many would you like?
