Research

How come I do research every morning?

Better than holding it in.

Otherwise, there might be a wicked fart.

#1 fart is silent and non-smelly. Undetectable.

#2 fart is audible and non-smelly. You can hear it so you have time to avoid the smell, but there isn't any smell. You know who did it.

#3 fart is audible and smelly. You can hear it, and know who did it, so you can prepare for the smell, which gets you. However, since you know who did it, you can blame that person.

#4 fart is silent and smelly. You can't prepare for it. It just sneaks up on you and gets you. Plus, you don't know who did it. Someone might blame you for it. It is wicked.
