Context: I was DMing for a group of five players playing a mission where they were in a swamp, on two rafts, a small one and a medium sized one.
Player 1: Okay, let’s start rowing.
Me: Okay, everyone roll for Athletics.
Everyone rolled. Two rolled high, one rolled okay, and then…
Player 4 (OOC): Okay, I… I got a 4.
Player 5 (OOC): Haha, well, I can’t get worse then that. *rolls a 2*
Me: *laughing* What’s your Athletics modifier?
Player 5: … -2.
Everyone is dying of laughter, Player 4 is almost sobbing.
Me: You decide to row with your shortswords. You stab your boat repeatedly. You swim over to stab the other boat, but your swords just bounce off. You realize what a mistake this is, and put your swords away. Okay, there are three of you in the water, roll Athletics to not drown.
The other two roll fine, getting an 18 and an 11.
Player 5: Okay, I won’t mess it up this time. *rolls* It’s… it’s a one.
Everyone screams, before I tell them to be quiet.
Me: Did you add your modifier yet?
Player 5: …No.
Me: So you’re saying… that you have one boat, that was built when you were blackout drunk, which you rolled one for constructing, and you’re trying not to drown in the middle of a swamp, but you just rolled a negative one.
Player 5: … Yes?
Me: Well then. I guess we’ll just have to end your session here then, ey? I wonder if it would be mean to open a portal underneath you to the water elemental plane…
Players: GOD FUCKING DAMMIT
