The version I heard was:

I'm a juvenile delinquent
I roam the streets from one to four.
I drink and smoke with other kids in town
waiting for my pickup to come.
I'm a juvenile delinquent,

My mother hates me, my daddy beats me,
as for my granny,
Swingin' on the outhouse door,
as if she owned it,
Swingin' on the outhouse door,
without her nighty,
Swingin' on the outhouse door.
