My personal favorite:

Is that a serif in your pocket or are you just happy to see me?

I have a couple of them here, I like the last one very much!:

That's because when Agfa bought the guts of the EyeWire site from Getty Images and ran their stupid little page spider over it, they neglected to capture images that were referenced in JavaScript or in file subdirectories. I should know where stuff is, because I built that site. Now it's nothing more than a shell of it's former self. Hey Agfa! Ever heard of a link-checker? Yeesh.

However, I did happen to archive that very page on my own site.

Oh, and there was another recent thread on the topic of typographic puns over here:

Lorem Ipsum Generator.

"116 words of the original 16th century Lipsum plus 384 additional words, carefully chosen from Cicero's very own 'De Finibus', bonded by superior scripting and utmost linguistic accuracy guarantee for the web's most random ... ah, randomness - 500 times sheer bliss for the typographically inclined. Ipso facto."

Su Wong marries Lee Wong. The next year, the Wongs
have a new baby.

The nurse brings over to the parents a lovely, healthy,
bouncy, but definitely Caucasian, white baby boy.

"Congratulations," says the nurse to the new parents.
"Well Mr. Wong, what will you and Mrs. Wong name
the baby?"

The puzzled father looks at his new baby boy and says,
"Well, two Wongs don't make a white, so I think we
will name him Sum Ting Wong."
