I wonder who will be the last person to think this wisecrack is an original observation? And yet, I think it should persist.
But then I've always thought the remark "Hot enough for you?" is funny. Now, I've never said it or heard anyone else say "Hot enough for you?" The first time I ever read it was in the 1960s in Mad Magazine. It was a Dave Berg comic strip showing one person after another say "Hot enough for you?" to a guy until he freaked out. (Would it kill Mad Magazine to have a website that let us search for old crap we remember from the 60s?)
Back then, I got the point the way a kid gets a point: So that must mean there are a lot of adults out there who keep saying "Hot enough for you?" and I need to know that's been said way too much before I ever say it or hear it. I was keen on figuring out in advance how not to embarrass myself.
And it seems everyone got the memo — if not from Dave Berg, then from somewhere. Whenever it was really hot, I thought about Dave Berg and how no one ever says "Hot enough for you?" and I got to thinking it really is pretty funny in the way that later generations might think it is funny to say "Could it be any hotter?" But I had to laugh to myself because no one ever said it.
So if you see me on the street some very hot day, feel free to say it to me: "Hot enough for you?" You don't even have to wait, you can say "Cold enough for you?" if you see me today. I'll be especially amused if you look like this:
Now, has it become clear why you should go ahead and keep up with the if-global-warming-is-real-then-why-is-it-cold jokes? They haven't gone away yet. They are at the stage in the life span of a joke where "Hot enough for you?" was when Dave Berg drew his comic strip. But, you may ask, doesn't that mean that people who don't want to be embarrassed should be getting the memo that these jokes cannot be told anymore?
No, I think we're at the stage where we keep up with the joke out of pure sadism to irk the folks who can't take it anymore. They are the earnest folk who want everyone to accede to scientific consensus and meekly swallow whatever remedies are prescribed. Taunt them!
