One guy learned the hard way that someone with nothing nice to say probably shouldn't say anything at all.

A customer at a Little Ceasars Pizza in San Francisco got an extra large beat-down Sunday after commenting on another customer's weight. According to the San Francisco Gate, police said the man heard a woman ordering and said she shouldn't be eating pizza because she's overweight. It's unclear if the guy made a joke or just blurted out a statement.

What is clear is that the woman got so upset that she want to her car to get a crowbar, but before she could beat the man with it, her son had already started punching the guy in the head. The two then took off, and police have not yet identified or arrested them.

The wisecracking customer was taken to the hospital and treated for minor injuries. If you ask us, he's lucky the son got to him before mama could.
