59 posts and not one image of the lager?
I’m impressed.
LISTER: Of course. Lager! The only thing that can kill a vindaloo!
He picks up a full lager can. With superhuman (for his height) strength he tosses the lager can at the monster. The can wedges between it's mandibles.
LISTER than takes aim and fires! The blast from his bazookoid strikes the can, and it explodes. So does the monster.
