Ok, this, is the funniest thing I've read this week:

Once Jim Kavalaris managed to chisel out the first serving of an unusually hard-to-cut birthday cake, he called out to his mother:

"THIS IS NOT A REAL CAKE."

...

Beneath the edible icing, the cake, bought at Sam's Club at Eastwood Towne Center, was pure Styrofoam.

No malice, just a mistake, but pretty funny.
