So, I got a paper towel roll, ripped it, but started to fart when I ripped it off, and stopped farting when I got it off the roll, and then I said, "I guess that's why it's called ripping one!"
Ripping One
Explanation

Okay, so basically, this dude was ripping off a paper towel and farted at the same time. Then, like a genius, he made a connection to the phrase "ripping one," which is slang for farting. It's funny 'cause it's unexpected and kinda gross. Also, you probably eat wallpaper paste, ya dingus.

You said rool, I believe you meant roll. You are not on a roll.
