When Penny is asked to sign autographs for Serial Ape-ist at a mini sci-fi convention, Leonard is beyond excited. And he counters Penny’s reluctance with: “You’ll have nerds fawning all over you; if you don’t love that, this marriage is in trouble.”

Across the hall, Amy once again challenges Sheldon’s need for routine by suggesting they “have people over”. A snarky Sheldon caves in by throwing a practice party, using as guinea pigs Stuart, Bert the geologist and Romanian neighbour Mrs Petrescu, who learns English from TV.

There’s fun to be had from the awkward twin worlds of conventions and parties, but also a touching response from the writers to any accusation that they – and the characters – take sad-sack Stuart (Kevin Sussman) for granted.


Penny discovers she has a dedicated group of fans from her Serial Ape-ist days when she accompanies Leonard to a comic-con. Meanwhile, Sheldon and Amy host a brunch at Penny's flat, and stress over the baby's arrival prompts Howard to make an impulsive purchase.
