There's a Mastery thread that has some good funny poems on it, started by much-missed Janet Kenny:

I posted one on that thread that still makes me laugh:
The Board’s Blare
Our Starver, Art without leaven,
Bellowéd be thy Fame;
Thy lingam come; thy will be gun,
On Campus as it is in Tavern.
Give us this day our Big Success.
Review at length our vacuousness
As we review those who evacuate with us.
And read us not in Profundity;
But circulate widely our drivel:
For Thine is the Foundation,
The Grants and the Glory,
For Sabbatical after Sabbatical.
Eh, men?
--Peter Russell, from his collection
Malice Aforethought
It's not brilliant but it's pretty good. "Evacuate with us" and "Eh, men" are my favorite parts. I like humor with a scorpion sting, like that famous epigram by Blake on what an epigram is.
I also tend to like short funny pieces because they're less work. As in Max's limerick examples above. What can I say? I liked Austin Powers, the first one anyway. I have a weakness for sophomoric bathroom humor and dirty jokes.
On another note, I love Byron's wit (see Janet's example that opens that thread) and Shakespeare's wild wordplay scenes.
