Because nobody ever told me.
While visiting India in 1959, Stewart reportedly smuggled the remains of a supposed yeti, the so-called Pangboche Hand, by hiding them in his luggage (specifically, in his wife’s underwear) when he flew from India to London, as a favor to Tom Slick.
Nobody ever tells me anything.
Thanks, Wikipedia, for the photo and for the information about Jimmy Stewart smuggling a yeti hand out of Nepal in his wife’s underpants.

His wife smelled of Yeti until her final days.
Next time, smuggle your own Yeti hand, Tom Slick you fucking asshole.
Maybe Jimmy Stewart freeballed.
Man, that Elwood P. Dowd really WAS nuts…
Is it just me or does this sound like the ideal backstory for the next Hellboy movie?
You gotta watch those guys in the trenchcoats, especially in mysterious Nepal.
“Feelthy pictures? Dime bags? Yeti hands?”
Couldn’t happen today.
If Wikipedia says it, I believe it.
The yeti hand wasn’t for this Tom Slick? Then it could never have become reanimated…
“Woul, Woul, aye, aye, say, aye, didn’t KNOW-UH it was in thar, Officers.”
Merry Christmas you old Yeti hand in my wife’s underwear!! Yeeeaaaaaay!!!
It’s also been Googled. Gotta love a rumor!
another great reason for x-ray scanners.
