So, this joke works only for natives who know that calf is not cow.

I guess a more accessible version would be toast… what do you put in a toaster?

Here's one for you:

A funny riddle is a j-o-k-e that sounds like “joke”.

You sit in the tub for an s-o-a-k that sounds like “soak”.

So how do you spell the white of an egg?

// All of these prove humans are subject to "context priming".

		My brain said "y" and then I caught myself. Well done! (I suppose my context was primed both by your brain-teaser, and also the fact that we've been talking about these sorts of things. If you'd said this to me out of the blue, I probably would have spelled out all of "yolk" and thought it was correct.)

Well, it works because by some common usages, a calf is a cow.

Many people use cow to mean all bovines, even if technically not correct.

Not trying to steer this but do people really use cow to mean bull?

		No one who knows anything about cattle does, but that leaves out a lot of people these days. Polls have found people who think chocolate milk comes from brown cows, and I've heard people say they've successfully gone "cow tipping," so there's a lot of cluelessness out there.
