George's answering machine

In "The Susie", George Costanza is avoiding his girlfriend Allison so she cannot break up with him before he can make a grand entrance at George Steinbrenner's ball. His methods of avoiding her include staying at home and not answering the phone when she calls. His answering machine message is a parody of "Theme from The Greatest American Hero (Believe It or Not)" as performed by George Constanza himself.

"Believe it or not, George isn't at home
Please leave a message at the beep
I must be out or I'd pick up the phone
Where could I be?
Believe it or not, I'm not home"

Fun fact: George's performer, Jason Alexander, is actually a good singer; he was told after the first take to sing as poorly as he possibly could so the song could sound funnier.
