What, you mean like:
Suddenly turning off all the lights, wedging the airlock door closed and ignoring any thumping on the hull for half an hour.
Hotwiring the "decompression alert" siren in the airlock for entertainment value on your return.
Playing Barry Manilow tracks in an endless loop on the EVA comms frequency.
Smearing the seat of the space bog with impact adhesive for entertainment value some time after your return.
Calling up and advising that they've found a hidden stash of fresh salmon, caviar, beer, vodka and weed in the Russian module, which they've already eaten, drank and smoked.
Faking up a Ground control communication advising of the outbreak of World War three.
Hacking the EVA suit systems and repeatedly cycling the internal temperature between "hinges of hell" and "balls off brass monkey".
Downloading one of those "real fire" screensavers, taping a monitor running it to the nearest porthole and then screaming for help.
Adding a pinch of salt and some yellow food dye to the output side of the piss recycler.
@any Astronauts reading this. Feel free. I like a laugh.
