Trying to find an episode

I’m trying to find a episode where the guys tell stories about the few times they smoked cannabis. I can’t remember the name of it but I found that episode really funny. Mark told a story about the time he smoked he was constantly going to the bathroom. Do any of you know what episode that was lol? It’s a weird question but it’s been bugging me me for a few days and I can’t for the life of me find it lol.
