A bloody fistfight between two drunken Wisconsin men was triggered by an argument over the TV comedy “How I Met Your Mother,” according to a criminal complaint.

Police say the brawlers attended the Green Bay Packers game Sunday afternoon, and drove to a bar afterwards (where they continued alcohol consumption begun at Lambeau Field).

After returning to their SUV, the duo got into an argument and began trading blows. The men eventually exited the vehicle and began trying to flag down passing cars, which brought them to the attention of the Rock County Sheriff’s Office.

Upon approaching the duo around 12:45 AM Monday, a deputy encountered driver Alan Huschka, 33, who appeared “extremely intoxicated” and struggled to keep his balance. Seen at right, Huschka, who had difficulty answering the cop’s questions, had abrasions to his face, one eye was swollen and nearly shut, and his shirt and pants were covered in blood.
