Electric Shock Treatment

I'm sure this has happened to most of you You come up with a brilliant thought Before getting a chance to write it down It vanishes just like a shot! You try and try so hard to remember Could it be some great new invention? Your mind's travelled south for the winter And has no capacity for retention You start to sweat and feel the panic Was it a marvellous new discovery? Was it going to change the way we live? The odds are slim for recovery You consider the electric shock treatment Sticking your finger in a socket Reconsidered 'cause your hands were wet Jammed 'em back into your pocket So you resign yourself and figure it's gone Then back it pops into your brain What you were trying so hard to remember Was your Mom and Pop's last name!
