Everyone Should Do the Jelly Mouse and Keyboard Prank

Somewhere in Finland, Tom's office colleagues decided to welcome him with the most delicious office prank this side of stuffing your monitor in a giant doughnut:

A mouse and keyboard keys stuffed in jelly. The note says "Welcome back, Tom!"

After seeing it, I wish they sold Jell-O in bucket sizes, so I can stick my head inside. [Thanks David!]
