“Why was the math teacher late for school?"/"He took the rhombus.”

The math term “rhombus” sounds like “wrong bus,” and there’s a pun:

Q: Why was the math teacher late for school?
A: He took the rhombus.


“Rhombus. Wrong bus?” was posted to the newsgroup alt.timewasters on January 12, 1999. “In Italy, I took a rhombus to get to the Vatican (Richard Lederer)” was in a “Puns of the Weak” post to the newsgroup alt.humor.puns on February 16, 2001. The math joke has been printed on several images.


Math Open Reference
