Cover art for Monkey On My Back lyrics by Aerosmith

the lyric "feeding that fuckin' monkey on my back" is probably instead "feeding that funky monkey on my back" in spite of about everyone on the net citing "fuckin'". Listen to it, I have about 1000 times. The word rhymes with monkey. A funky monkey would mean he is confused by it, fuckin' is he's mad. Either way, it ain't good.

This song comes on a fine album, "Pump." Part of the Aerosmith comeback starting in the later 80s, with "Permanent Vacation," and then "Get a Grip" after Pump came out. Aerosmith's best stuff, IMO.
