== Lyrics ==
=== Homer's Barbershop Quartet ===
Grampa: Old MacDonald had a farm.
E I E I O.
And on this farm, he had a chick.
The swingin'est chick I know.
With a wiggle wiggle here
and a wiggle wiggle there.
===Whistler's Father===
 (Whistles the tune of "E I E I O")
Now do it backwards.
(Whistles the tune of "O I E I E")
