I have to record this because it's just too funny to allow it to slip into the oblivion of memory, at least for someone as utterly amused by corny jokes as I am.

During a meeting last week my boss's boss revealed that he also likes corny jokes. The one amusing him the most last week was this one:

A: Knock, knock.
B: Who's there?
A: Impatient cow.
B: Impati--
A: Moo!

So he told this one, in the middle of the meeting after one person had interrupted another (Accidently, of course. We're a friendly bunch of folks, and usually like each other just fine.)

During a break I started thinking about knock, knock jokes some more, trying to think of a good math/computer/generally geeky one, and he responded to my pensive look by collaborating with me on some more. We developed this lovely series of them during the five minute break.

[Impatient Cow Joke]

A: Knock, knock.
B: Who's there?
A: Impatient narcissist.
B: Impati--
A: Me!

A: Knock, knock.
B: Who's there?
A: Impatient sheep.
B: Impati--
A: Ewe! (You!)

It's even funnier if you've just had a bunch of sugar and/or coffee, and/or are sleep deprived.
