Go to your room and stay there until I tell you to come out. (Also, no supper for YOU tonight.)
Really Pissed-Off Mrs. Klunky, Mother of Sorta
Seriously, I cannot remember any April Fool's pranks being played as I was growing up....other than goofy ones in grammar school along the lines of scotch-taping a "Kick Me" sign on the back of an unsuspecting classmate.
Maybe these shenanigans were discouraged by school and parents upon pain of punishment?
