Not so satisfying, but still funny --
My blue MK II roller was delivered by a semi, and on the level above mine at the rear was a blue '05 Ford GT. The driver and I rolled mine out of the truck and parked it in my driveway across the street. We were closing up the truck when a local plumber pulled up, stopped, blocking the street and ogled the Ford GT's rear end.
While he was doing so my driver said "Hey, did you notice what's in the driiveway over there?". The plumber looked over and said, "oh, well, what's that?" "It's a
real GT40!".
"Oh, I thought that was a Pantera."
