Lyrics:

Now this is a song about Pavlov
Now he discovered that you could flash a light
And ring a bell
And you could get human beings to commit
Cunny-lingus
But then
An even more amazing fact emerged
He found out he could stop flashing those lights
And stop ringin' those bells
And they'd still commit cunny-lingus

Well every time I smell pussy, I go weak at the knees
Hands start a-shakin, and my legs a-freeze
Lights turn green, and my mouth salivates
Pour another gallon in my Buick 88

Cause Pavlov says it's all right, all right
Pavlov says it's all right, all right
(Something something something) tonight
