Best April Fools joke you have played on someone or that someone has played you

The one where Mitch Hedberg died

Quite a few idiots fell for this joke from LSU

Sent folks to the April Fools Day parade downtown before.

My roommate was being a real dick when we lived together in Kirby Smith dorms. For April fools I took all of his clothes and towel out of the bathroom while he was in the shower and locked our dorm room door. Two hours later when I came back he was gone but my dorm was still locked. Later that night he came back and was pissed and wouldn't tell me how he managed to get clothes. Years later he admitted to having to run down the hall, go up two flights of stairs to his friend's dorm, and wait in the shared kitchen area between the dorms for his friend to get back from class and let him in. All while butt naked.

Not April Fools, but the best I have ever been "gotten":

Between Thibodaux and Houma, there was an old plantation home that had fallen into disrepair (it's since been renovated). It was long rumored to be haunted.

When we were teenagers, A couple of buddies told me and another friend that they had gone in the night before and had heard a bunch of strange noises, and wanted to know if we wanted to go that night to check it out. Of course we did!

So we wait til after dark and sneak into the house. Don't hear anything downstairs, so we go upstairs and sure enough, we start hearing chains rattling and ghostly moans. My friend and I, scared shitless, haul arse out of the house and are running across the yard when all of the sudden we hear the sounds of laughter coming from the house.

It was a few other of our friends that had been hiding and waiting with chains.

Mother frickers!!!

I once told an NCAA coach that we were going to fire the guy we had and hire him. The dude was pretty excited. Then people got mad at me, so I had to keep the guy I had, even though he fricking sucks, and tell the other guy he wasn't getting hired. Funny stuff in hindsight

When I was a sophomore in high school, I told my mom I got a girl pregnant and didn't even remember her name. She legit started crying and told me "Joey, your life is over." My brother was laughing in the living room and when I finally told her April fools, I got a big slap then a big hug.
