(That's an evo in-joke.)
72 platypusses? Now I know all. ;) I wonder what I get?
Tie me kangaroo down, Clyde.
Mind me platypus duck, Bill,
Mind me platypus duck.
Don't let him go running amuck, Bill,
Mind me platypus duck.
All together now!
Tie me kangaroo down, sport,
Tie me kangaroo down.
Tie me kangaroo down, sport,
Tie me kangaroo down.
