Patrick Cassels, a.k.a. Pat or Pat Cassels, is the former Head Writer at CollegeHumor. He hails from Poughkeepsie, NY, and spends a fair deal of time writing articles and analyzing video game movies. Traces of his brilliance can be found in all corners of the internet. He is featured in several Hardly Working and Jake & Amir episodes. His many appearances have caused commentators to create a catchphrase featuring him: "Don't be like Pat Cassels."
Although Pat Cassels no longer stars in CollegeHumor, he still makes occasional appearances as part of running gag that Mike Trapp killed Pat Cassels.
