Yeah...I always said that a PEE-can is what you used to put under your bed at night...
True, that. Back in the day, the difference between rich and poor men was described thusly:
The rich man has a canopy over his bed.
The poor man has a can o’ pee under his bed.
Then there was the little boy whose fastidious mother gave him the euphemism of “whisper” to say instead of saying he had to pee. One night, sleeping with his grampa he told Gramps he had to whisper. Gramps sleepily told him to come whisper in his ear. So he did.
