My version is somewhat more alcohol inspired *G*

It has to be sung /to/ Noodle the cat:

Noodle Doodle went to town to buy a little fishy
Put it in a paper bag and brought it to his dishy
Noodle Doodle ate his fish, he thought it was delicious
Noodle Doodle had his fish and then he licked his whiskers

*and you must, repeat MUST be drunk to sing it. or me.
