I'm not much of an April Fools person, but the only things I could think of was:
(1) Pretend that one of my mother's cats scratched me at 2 AM and that I was bleeding from then to 10 AM
(2) Say there's a Pikachu on the computer screen, only for an Emolga to be there
(3) Telling my mother that there was sport on a television channel the entire day. Believed me until she turned the television on at about 14: 30 PM.
(4?) I said my cat was inside, and my mother didn't believe me until I took Simba to her. I think this doesn't count, but I'm not certain.
I'd probably have pulled another one on the Cave Story Tribute Site Forums, but my ability to post was revoked until end of August, so I'll wait until next year.
