Moshe was at his golf club and went into the clubhouse
to see whether anyone could offer him a lift to Manhattan.
His own car was in the shop being serviced. "Sure," said
Irving, "I'll give you a lift. My Rolls Royce is just
outside."
As they're driving along, Moshe says, "Irving, what's
that thing on the dashboard making a soft humming sound
all the time?"
"That's my digital clock."
A few minutes later, Moshe asks, "And what's that thing
on the dashboard moving up and down?"
"That's my tachometer," says Irving.
Then a few minutes after that, Moshe starts to ask,
"What's that...." "Hold on a minute, Moshe," says Irving,
"I can see you've never been in a Rolls Royce before."
"Yes I have, but I've never been in the front seat."
