Dilbert from yesterday:
Would this be a better joke if the pronunciations were closer? I'm not sure.
My favorite example of phrasal homophony:
There was a cranky TV set in the common room of a house I lived in. I changed the channel to tune in a baseball game, using a knob on the set because this was in neolithic times before remote controls were normal. The reception on the new channel was kind of jumpy and static-y. One of my friends, watching from a couch across the room, said "Did a little little little help."
I said "Huh?"
What he meant, of course, was "Diddle it a little, it'll help."
