The blue-eyed husband is a man married to the blue-eyed wife.
He once tried to kill Homer Simpson after he found him flirting with his wife, where he was soon stopped by Homer, who squirted lime juice in his eye. He later attempted to kill Homer again while he was dancing with Marge, just for his wife to knock him out for a short amount of time so Homer could flee. He soon woke up and started hunting for Homer, Homer was soon able to convince the blue-eyed husband to back off.
