Okay, one more related to heat, which may not even count...

Today's word usage may branch us into a new category of puns; at least I don't think I've catalogued one like this before. It involves the mis-spelling of a word, which results in a homonymic pun with the correctly spelled word. You'll see what I mean in a second, and you'll have to help me decide if it counts.

As we came home from the grocery, just before she pulled into the driveway, my wife hesitated, trying to decide on which side of the driveway she should park based on which car in the garage she should park behind. I said, as I pointed toward the back of the car: “Whatever you decide, do it soon, because this meat is bakin'.”

I said "bakin'" just like that--not "baking". It sounded just like bacon. So, it wasn't a pun of just one word having two meanings, it was a case of two different words, sounding the same, creating the pun. Does that count as a pun? You help me make the final determination. I would like to add it to my catalogue, because I think it should count. But I'd like your opinion.
