“Yer Mom was a ________”

… he traded the fifth for a whore

… the four is an Int I adore

… three third bits is all I afford

Hadn’t seen this one before but I saw this in a book:

There once was a man from Peru,
Whose limericks stopped at line two

and then later in the same book they had

There once was a man from Verdun

My bandwidth is crappy through Tor.

Too much exposition’s a bore.

OR

Though a quatrain’s a ditty,

My pay’s itty bitty.

If you cut prose apart, so as to make more,

Perhaps, one day, I’ll afford my lost oar.
