Replying to In-class-farts

I am in my calc 3 discussion class, and I have a real seat-cracker building up in me, the kind that makes you move around cause it is so uncomfortable to hold in. The problem is thatI already showed up like 5 minutes late for this, and can't exactly get up to go to the bathroom
This puppy will be neither silent nor smell-less, and I still have like 35 minutes of class. Shit sucks man, feel free to talk about your inopportune farts as you see necessary
