Because they had planned to do it during the week but never got around to it, Richard asked if he and Sal could have their temperatures taken rectally to determine which of them had a warmer anus. After some coaxing, Robin agreed to take Richard's and Sal's temperatures and they removed their pants accordingly, an act which prompted Will and Ralph to slap Richard's backside with their hands. Sal reported he wasn't bothered with the sensation once the thermometer was inserted into his backside, while Richard commented it felt "wild" and that his "anus must be real sensitive because it felt like the thermometer was being twisted" when it was inside him – although no one was touching. Robin then took out both thermometers, and announced Sal's temperature was 98.6 degrees, and Richard's was 98.5 degrees.
As Sal began taunting Richard because he "won" their competition, Richard sprayed him with silly string, which prompted Sal to put the thermometer that had been inside his rectum into Richard's mouth. When Richard returned the favor to Sal using his own thermometer, he added, "That's what you get, motherf'er. It's a shit for a shit."
