You're about to lay down the moves and impress these ladies when the woman talks to you, freezes in place, and puts on a confused face. You can't understand why until smoke starts to rise from her pores and her skin catches fire.
"Is this normal?" you ask her friend.
"No," she says, "this is the first time I've seen this. I heard about an outbreak of spontaneous combustion in Europe, though; they say it's really contagious."
"Oh, yeah?" you answer, "I hadn't heard about that."
"Yep," she says, "it's true," then bursts into flames herself.
"Well, damn," is about all you have time to say before your skin starts to smoke as well.
