Big Al's Burgers and Dogs in Old Town Fort Collins was the victim of theft recently.  They didn't lose any money or equipment, but rather a painting by a local artist.

The walls of Big Al's are lined with local artwork, which really gives the place a great feel.  Included are three paintings of "Full House" characters Jesse, Joey, and Danny (remember them?); and now, Uncle Joey is missing.

I get that "Full House" is nostalgic for many of us, but does that justify stealing?

No.  The answer you're looking for is no.
