Once upon a time, there was an acid head
Spent his time a-tourin' with the Grateful Dead
Accompanied by a monkey in the passenger seat
Watching all the drugs the acid head would eat

One day, the acid head wanted to smoke some hash
Went into the trunk to find his pipe and stash
The monkey jumped up in the trunk and beat him to the toke
And ate ninety hits of acid and a gram of coke

Monkey full of acid, right on time
Monkey with a razor blade, cuttin' up lines
Monkey full of acid for the very first time
Left the acid head with a worried mind

The acid head called up his roommate on the phone
To tell him all about how his stash was gone
"Get the dealer on the line and tell him that we're f*cked
'Cause the monkey's crapping everywhere, this totally sucks"

The dealer got the message and he set 'em up right
Brought enough to party on the rest of the night
Now everybody's laughing while they're passing 'round the bowl
'Cause the monkey's full of acid and he's out of control

Monkey full of acid, etc.
