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 GIFs.
