Diet Coke

Diet Coke is a running joke between hosts. Starting out as MatPat's favorite drink, however, that title expired shortly after Food Theory was created in the episode "I QUIT Diet Coke!" where it was decided that Matthew prefers Harris Teeter or generic while label diet soda over Diet Coke. Since Matt's retirement, Diet Coke is still used as a running joke between the hosts, such as in the Film Theory open for "I Found Dune’s DIRTY Little Secret!" Where Lee is converted into Diet Coke instead of water.
