The Big Bang Theory

The Bachelor Party Corrosion

Series 9 - Episode 3 The Bachelor Party Corrosion

Saturday 8pm - 8:30pm E4


It may be damning with faint praise to say this story is the funniest of the series so far. It’s only episode three, after all. But with all the regulars featured in roughly equal measure and an occasion to celebrate, the writers’ gag reflex seems to be functioning again. Raj and Howard set out to kidnap Leonard for a belated bachelor party – and end up having to drag Sheldon along. Their getaway car actually was owned by celebrated physicist Richard Feynman – according to the production card at the end – and you’ll be glad to know it was unharmed in the making of the show.

The girls try to take Penny out for a hen do, but she says, “If I want to see a naked man dance around, all I have to do is flush the toilet while Leonard’s in the shower.” Amy’s celebration cookies sound jaw-dropping, but as show-stoppers go, Sheldon's falsetto Freddie Mercury is hard to trounce.


The guys' science skills are put to the test when they get a flat tyre during Leonard's surprise bachelor party weekend in Mexico. Meanwhile, the girls finally force Penny to break the news to her family that she has eloped with Leonard. Keith Carradine guest stars.
