Everybody loves math jokes!
I swear this is nearly verbatim.
Roommate says, “I got a buncha holes in my pants,”
and I cheekily say “well, three at least, otherwise it would be a skirt!”
He replies, “Yes, I don’t suppose you could have pants with just one hole could you?”
“Sure, you could have those feety pyjamas!”
“Hmm, if you sewed the tops and bottoms of two pairs of pants together you could make a kind of Möbius Pants that, topologically speaking, wouldn’t have any holes at all.”
“When you take them off, is it a Möbius Strip?”
“Yeah, and when you wash them, they’d be Klein Pants!”
We should not be allowed in public.
