EPISODIUM
Eric and Annie reluctantly allow Mary to go out with Robbie, on the condition that they double date with his younger brother Rick (guest-star, Lance Bass, ""N'SYNC"") with Lucy. Meanwhile, Simon and Nigel buy several packs of cigarettes for a class project to prove how easy it is for children to buy tobacco. Also, Ruthie works out her own secretive science project and John invites some female neighbors over for dinner to take Matt's mind off of Shana.
