Joke: Man in ecstasy...

He was in ecstasy, with a huge smile on his face, as his wife moved forward, then backwards, forward, then backwards again, back and forth, back and forth...in and out...in and out.
It was going on 20 minutes at this point...
Her heart was pounding...her face was flushed...then she moaned, softly at first, then began to groan louder.
Finally, totally exhausted, she let out an almighty scream and shouted:
"OK, OK! I can't park the damn car! You do it, you smug bastard!"
