This year's calendar fleeces me of a splendid opportunity to play a practical joke on my students because April Fools! falls on a Sunday.
Our class has a routine. Every day I post the night’s homework on the chalkboard for the students to copy in their agenda books, but on April Fools! I put some extra stuff up there............not enough to make it obvious, but enough to cause consternation. I play it straight for quite awhile, then yell, "APRIL FOOLS!"
DURN! I'll miss that!
