Fridge magnet + flash drive = ?

I'm sure someone's going to laugh at the stupidity of this question, but I'm going to ask anyway: Can several-day exposure to a refrigerator magnet corrupt the data on a flash drive? I'm putting together a small package to mail to Canada, including those two things, and they'll be smushed up next to each other for a few days at the very least.

I'll just point out that the iron in your blood isn't magnet and can't be pulled out with a magnet :p

That said, flash drives are fine around magnets. I've accidentally gotten flash drives stuck to multiple-tesla magnets before with no effects on the data.

"There's nothing magnetic in flash memory, so [a magnet] won't do anything," says Bill Frank, executive director of the CompactFlash Association. "A magnet powerful enough to disturb the electrons in flash would be powerful enough to suck the iron out of your blood cells," says Frank.

So yeah, `nokari's comment.

No.

To have any change of damaging a flash drive you would need a rapidly changing magnetic field that could induce a significant current. A static magnetic field wouldn't do anything unless it were powerful enough to actually pull any iron components of the flash drive enough to damage it.
