A really not fun fact: the original meaning of the term 'faggot' was 'sticks to be burned', which also explains the British slang for cigarette 'fag'. So this joke, such as it is, kinda glibly ignores, or maybe even leans into, a whole history of brutal homophobia in which gay people often paid with their lives. So sorry to get all schoolmarm on you, but this joke kinda sucks.
