A wooden-like barrel that produces pleasurable vibrations to anyone who deposits $0.50. The vibrating element is arranged in such a way to imply that the vibration is for feet.

Proper use of the Barrel of Fun requires the rider to sit on the vibrating element.

The Barrel of Fun is especially pleasurable to those of the female sex.
Ralph: Roxanne, you seem to be enjoying that Barrel of Fun a little too much.

Roxanne: I am just getting primed for later when we get back to the Roxy room.
