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.
Maggie/Homer: (Whistles the tune of "E I E I O")
Lenny (Speaking): Now do it backwards.
Maggie/Homer: (Whistles the tune of "O I E I E")
Lenny: Now sideways.
Homer: Hey, come on, she's just a baby.
Moe: Who is?
Homer: My talent.
Moe: Makes sense.
