Many many years ago…
Mmm-hmm
met a lady named
Uh-huh
but they did an
uht-oh
and when she asked if the man if they should keep the baby he said,
“unh-uh”
so she tried to put up the baby for adoption, but changed her mind, and the baby thought
“whoo-hoo!”
When the baby’s mom would change his diapers, the smell made her exclaim,
“phew-wee”
As they baby got older, his first words were,
“nyah-nyah”
then
“nanner-nanner”
and
“boo-boo”
Many years passed, and the baby grew up into a man. He took an interest in acting and later won several Academy Awards. He had the privilege of meeting Busta Rhymes once, who told him,
“Whoo-ha, I gotcha all in check!”
and the man laughed. He then told Busta his own catch phrase,
“Hoo-wah!”
which he would shout when he smelled the perfume of every hot looking woman he saw.
So, Dopers, could aha be a possible distant relative of none other than, Al Pacino! You decide… 
Huh?
Hmmmmm.
