Can be fun. I like “playing” with words. Things like Malaprops,
There’s the classic 3-Stuges “I resemble that remark.”
Or “I can’t dismember what he said,”
Or, sometimes just transposing words can be a little interesting, like “I don’t stand under that” instead of “I don’t understand that.”
I especially like the ones that form real words, but sometimes ones that make nonsense words are funny too.
Some of my favorite Spoonerisms.
