Timberlake referenced his "Dick in a Box" sketch by putting a gift-wrapped present in front of his crotch, and when he dropped the box, both guys began singing the theme song from the show's animated "Ambiguously Gay Duo" segments. 

The bit also saw a visit from Molly Shannon's Mary Katherine Gallagher, who got a little support from the guys when she got nervous.
