Calvin was sitting in class one day when he started to absolutely rip ass and loud and horrible-smelling as humanly possible.
Michael: Dude, Calvin has the worst case of Gas Ass ever!
Dude: I know!
Calvin has Gas Ass later that night and is absolutely ripping ass at the dinner table.
The Dad: Calvin, that smells f*cking terrible, what is your sh*t?
The mom then passes out while the sister and the dad evacuate the room while Calvin has a big smile on his face.
