Not an april fools joke, but hubby's best freind likes to prank myhubby.(well, he likes to prank whoever) One time, they were driving in ohio, on the interstate. Hubby had fallen asleep in the passenger seat. His buddy, being the wiseguy that he is, honks the horn, slams on the brakes and swerves. (the bud is driving). The other buddy who was in the back seat, shines a flashlight right into hubbys eyes while all this other crap is going on. Hubby is scared cr*pless, thinking they just got into an accident.
Same bud pranks his wife,--the wife is going on a trip with her coworker, and they have to share a room. Bud puts a whole bunch of "toys" (if ya know what I mean) in his wifes suitcase.
There's more, but I don't have time rightnow.
