That's funny. Reminds me of a time the guitarist in my R&B band kept starting a tune way too slow. We all kept saying, "Man, that's too slow!" and he would say, "You just haven't heard the original.... this is the tempo!" I said, "Man, I have the original in my car on CD! I bet you $20 you're playing it too slow! It should be here... (pat knee at correct tempo)." So we figure out what tempo he thinks it's in using the sequencer on my keyboard and do the same for me. Then I go out to my car and get the disc and play the tune over the sound system on a break.
Guess who was right?
Then he tries to tell me that CD players play discs at different speeds! I said, "Ok, let's go out to my car and see what the CD player there sounds like... for another $20!"
He didn't go for that!
