Strutting out of your tent in a Hawaiian shirt, hula skirt, and coconut bra, then disconnecting Frank’s oxygen tank.
Waking up the sherpa to see if he wants to raid the Girls Tent.
Replacing the signpost marking the southern Nepal route with the one for the more technically challenging northern Tibet route, then changing the signpost of the northern Tibet route to WIENER MOUNTAIN.
Grabbing Frank’s ankle while he’s scaling the Geneva Spur and kinda shaking it around going, “Avalanche, avalanche!” Trust me, he’ll get it.
Strutting out of your tent in an old-timey elevator operator costume and yelling, “Anybody going up?” (Tip: one of the keys to making Everest fun is to pack a lot of cool costumes.)
The ol’ carabiner-to-the-testicles gag.
Hiding under the snow for a few hours before popping out to yell something offensive.
If you’re caught in the path of an avalanche, get one last solid laugh in by flossing until you’re swept to your death.
Less of a prank, but there’s something about being buffeted by 120-mph winds on the Rongbuk Glacier that makes it the perfect time for a really good Left Shark reference.
Yelling “just kidding!” as you discharge your flare gun into a yak.
Pretending your grappling hook is your penis and then firing it up an ice wall. This one’s great because it’s one of those pranks that also really makes you think.
Releasing three chickens labeled 1, 2, and 4 into a glacial ravine.
It’s a pretty good prank to switch climbers’ backpacks, but if that’s too much work you can just kick them around for a few hours until you get tired and fall asleep.
Making Frank pee in his sleep by putting his hand in a glass of warm pee.
All of these pranks are going to hit a lot harder if you’ve established yourself as the ascent’s “funny guy.” Don’t be afraid to loudly say things like “I’m not carrying that — I’m the funny guy,” or “Funny guy needy extra rations.”
Discharging Frank’s flare gun into a yak (just in case anyone missed it the first time).
Between the suffocating altitude, treacherous crevasses, and slippery ice walls, it takes an entire two months to scale the world’s tallest mountain. It’s close, but this should give you enough time to come up with a really smart Right Shark reference for when you reach the top.
