'Readin' and 'ritin' and 'rithmetic, plus some physics and chemistry

Both Stan and Phoenix have terrific posts today -- both major funny -- both originated with students.

When you read Stan's post, you might not get the joke right away. Give it a little thought and you'll say "Of Course!"

Phoenix's post provides more explanation about what his student did -- but be sure and read the comments.

Fun stuff for Friday the 13th!!!
