Taken from an embarrassing celebrity encounter with Tim Curry and fragrant soaps, the phrase "That'll give you... er... bees." has evolved to become a consoling response to embarrassing anecdotes. It can also be just "That'll give you bees" or simply "Bees"
Bob: And then they depantsed me in front of the entire history faculty!
Amy: *Consoling nod* That'll give you bees.
John: I can't believe I just did that!
Matt: Bees, man, bees.
Shop attendant's mind: Those soaps are so fragrant, we sometimes get bees in the store thinking they're flowers.
Shop attendant's mouth: That'll give you... er... bees.
Tim Curry: Oh indeed.
