I managed to get through the whole of April Fool's Day with only one joke being attempted on me-- and fortunately, I caught on before I started tearing out my hair. (The joke involved a road trip with a bunch of 4th-6th grade students. Yikes!)
I didn't bother trying to hand any out, though... I must have run out of creativity. I passed along one of my brother's favourites-- Vaseline on the doorknobs-- to a coworker, who intended to try it on her children.
My brother always thought April 1 was the day he could do whatever he wanted to the rest of the family and get away with it. Silly brother-- he could do that any day of the year. :)
