Expire Erect - S4-E5

Answer: This is answered in the second episode, where we meet Ched who's clearly not a genius. Given this first episode was originally written as the penultimate one of the series, and tweaked as the premiere later, it makes more sense why that line might be a throwaway by Bruce, given if it was episode 8 as intended the audience would already have met Ched and understand how he's not being remotely serious.
