A girl and a guy, heading from George Brown College - which means they actually graduated from high school.
Girl: Wait, so March has 31 days?
Girl: Every year?
Girl: Since when?
Guy: Since always!
Girl: Ok, but I thought the rule was that if the month's name is short - like March or May or June - it only had 30 days. Big months like November and December have 31 days.
Guy: Uh, no.
Girl: Crap! Please tell me there's a September 31st! I just sent some post-dated cheques to my landlord!
Guy: *Pauses* Just kidding! April Fool's!
Girl: OMG! You totally got me! I was this close to calling my landlord and making an ass of myself!
Girl: *Pauses* Ok, so there is a September 31st?
Guy: Oh, definitely.
