Fans of a certain Saturday Night Live alumna can simma don na. SNL is at long last airing a Best Of Cheri Oteri special on Saturday, Sept. 4 (11:30 pm/ET). The 90-minute guffawfest will showcase such classic Oteri characters as Arianna the Spartan Spirit Cheerleader; prescription-addled Collette Reardon; Morning Latte ditz Cass Van Ry and, my personal fave, Rita "I keep it!" Del Vecchio. Prepare to wet yourself.
