A Boy in a Man's World is the second studio album by Mucky Pup.

The album features a re-recorded version of "U-Stink-But-I-♥-U," which the band had previously won a Bloom County songwriting contest with.

The album featured cover art by future DC and Marvel comic book artist Nelson DeCastro, who had previously done T-shirt art for the band as well.

Several years after the album went out of print, the band pressed their own version of the CD to sell on their website and at their occasional reunion shows.

This version of the album contains five additional live songs not released on the original pressings.
