I'm sure I've posted these before . . .
A mathematician named Crottle
Poured water into a Klein bottle.
. . When asked, "Do you doubt
. . That some will run out?"
He replied, "No, I don't. Quite a lot'll."
To a tightrope walker named Zekund
The "a" due to gravity beckoned.
. . His performance was great
. . At about 9.8

There was a young lady named List
Whose mouth had a funny half-twist.
. . She'd turned both her lips
. . Into Moebius strips.
'Til she's kissed you, you haven't been kissed.
A girl from the vast Fourth Dimension
Has a sex life beyond comprehension.
. . With length, width and height
. . She's an utter delight.
With her fourth ... it's too marv'lous to mention!
And one I didn't write, but I love it dearly:
There was a young bard from Japan
Whose limericks never would scan.
. . His poems all tend
. . To come to an end
Abruptly.
