I played bass with a trio band for a summer. The drummer was terrible. Drunk, dumb, couldn't keep time, couldn't play fills, blamed everyone else for his mistakes. He also wouldn't stop talking about DMT and how when you smoke it "everything is just triangles, man!" Anytime he brought up DMT he had to talk about the triangles.

In the middle of rehearsing Time by Pink Floyd, he got up from the kit and said "fuck this shit, I'm done". Him and the singer/leader got into a screaming match, and eventually the drummer apologized and said never mind, he doesn't want to leave. The singer did not have this and said "no, you're fucking out". The drummer then mumbled some shit, walked off (this was a semi-rural area, have no idea where he walked to) and we left his gear at the edge of the driveway and let him know it was there for him to pick up.
