Marisa and Sam discuss Lizzie McGuire Episode 220: Xtreme Xmas, which first aired December 6, 2002. Steven Tyler makes a surprise celebrity cameo appearance as Steven Tyler Claus, but Marisa and Sam feel that he was largely underutilized. This was also the first episode Sam has watched without Miranda, and shocker, it all started to fall apart. Plus, they debate whether his rendition of Santa Claus is Comin' to Town holds water against the Zooey Deschanel Elf version.
