Two songs with the same title and the same theme. And as different as night and day.
From 1967, please enjoy barking mad British eccentrics The Bonzo Dog Band and "I'm Bored."
And from 1979, consider if you will the irrepressible Iggy Pop and his meditation of the same name.
To be honest, I've never been able to decide which one of these I love more. Iggy's rocks harder, obviously (great guitar work courtesy of Scott Thurston, currently of Tom Petty and the Heartbreakers, which always amuses me). But the Bonzos track is just drop dead funny on every level.
