Quick,
call Matt Groening and explain this to him.

(Can't find the right video, so this will have to do.)

Ah. I'd not seen that episode of Futurama.
Though your description applies equally well to the titular hero of Dolemite.

That's the gag,
but I couldn't find video of the relevant part of "Jurassic Bark", so had to make do with the rehash of the joke from another episode.

Over-explanation has rather killed my attempt at a humorous reply. :(

Shall we flog it a bit more to really extract the last ounce of humour from it?

I think I'm spent.
This has never happened to me before, honest.

I looked this up hoping it was about a tiny insect waiting for his giro.
