Some Linux developers run into some Microsoft developers at a train station. They're all going to a trade show a couple hundred miles away... The microsoft guys buy 1 train ticket each, then they watch the Linux guys buy only 1 ticket in total. "Huh? 1 ticket? Aren't you all going?" "Just wait and see" the Linux guys say. So they all get on the train... the conductor comes around, and the Linux guys cram into the bathroom. The microsoft guys give the conductor their tickets, then watch the action. The conductor knocks on the bathroom door "Tickets Please".... One of the Linux developers open the door a crack, and passes the conductor one ticket... "thanks you" the conductor says and moves on. The Linux guys then take their seats and smirk at the MS guys
After the show...
The Microsoft guys figure they're going to try that new trick So they buy one ticket The Linux guys decide not to buy a ticket at all "Huh? no ticket!?" "Just watch and see" one Linux guy says.
So they all get on, and the Microsoft guys cram into a bathroom immediately, and wait it out for the conductor One of the Linux guys walks casually up to the bathroom door and says: "Tickets please"
