First Guy to Get a Boner Loses - S4.E1

Kenny and Spenny compete to see who gets a boner first. They both put on speedos and throw whatever tactic they can at each other. Spenny brings his cousin Bianca in a bikini to Kenny's room and try to arouse him while Kenny tries to get Spenny so frustrated that the blood rushes to his genitals. That fails but Kenny gets an injection that stops him from getting a boner for a week.
