There's a chap that posts to an academic list-serv I receive called 'Charles Wankel' so near but yet so far...
Once, when I was a painfully shy teenager, my dad was telling how fast a neighbour's new car was. I asked him what type of engine it had and he replied with what seemed a very harsh
non sequitur "He's a big self-gratification artist!"
I started blushing. One of those deep, burning, teenage blushes that gets worse and worse the more you think about it...

I was really shocked to hear my dad call him that because no coarse language had ever been allowed at home. Still, if we were going to be honest about him...
"Yeah dad, he is a
total self-gratification artist but I'm asking what type of engine his car has?"
"
WHAT! Wankel, boy, the engine is a big Wankel!"
Oops, I'd never heard of a
Wankel engine...
