Olden People:

Marc : But I need to go anyway, so may kill two birds with a stone, or just one. Either way, birds will be killed.
Marc : Stupid expression
sunnyfreakingday: yeah, what did the poor birds ever do?
Marc : Were people ever that stingy with stones?
Marc : I mean, who's ever said "I'd really like to kill and eat that bird, but I've already killed one bird with this stone..."
Marc : Of course, nothing from the olden days makes sense
sunnyfreakingday: yeah, those olden days.
Marc : Pop Goes the Weasel...what the hell does that mean?
sunnyfreakingday: i always pictured throwing the stone once and somehow magically hitting two birds.
sunnyfreakingday: like a rebound or something
sunnyfreakingday: which actually makes less sense, i think
Marc : Yeah, me too.
sunnyfreakingday: now, saving the stone and hitting another bird another day, now that makes sense
Marc : But I wondered why you couldn't just pick up the stone if you missed the bank shot and kill the second bird later
sunnyfreakingday: but, like you say, who's that stingy with stones?
Marc : I dunno
Marc : Olden people
sunnyfreakingday: oh, those olden people
sunnyfreakingday: i'm shaking my head.
Marc : Olden people sure liked barrels
Marc : That's one thing I've learned from video games
sunnyfreakingday: oh, indeed they did
Marc : And inns
sunnyfreakingday: yes
Marc : Did you tell you I'm addicted to an RPG?
sunnyfreakingday: no, but it's all coming clear now
