I need about 50 USB flash drives, cheap and fast

I need to play a practical joke on a coworker, and I need about 50 thumb drives. I can go as small as 8mb, and have no need to go above 32mb. Everything I find online wants to give me quote for customization, but I just need a box of drives. Does anyone have any sources or ideas?

 

Having trouble finding small ones, and don't want to spend a few $100.

Sort of a long story, but here goes:

I work very closely with a VP that manages a department very similar to mine. We try to coordinate on most all work we do, though we don't report up through the same organization. Last week, she had her quarterly department meeting, which I attended with my team. Leaders from her organization got up to speak about their accomplishments as they've always done. When my turn came, I chose a different path. We'd just returned from our National Sales Meeting, and I decided to share photos, on the projector, of this VP dancing on the stage with the band while singing "Oh Ricky You're So Fine" at the top of her lungs. I wanted the department to know that they'd been represented the sales meeting. I even had the song recorded so I could play it through the mike. The VP promised payback.

Next Thursday will be my payback. We have the annual awards meeting for our departments, it will be about 140 people and will include our executive leadership. It's not a small thing, we're a Fortune 20 company. I don't know what's coming, but I know it's coming and it's going to be in front of god and everybody.

The flash drives will be a deterrent. Last week I showed the pictures of the partying VP, but I didn't show ALL the pictures, and she knows it. The best ones haven't been displayed yet. I want to be able to show her a box of flash drives, and assure her that if she goes forward with whatever payback she has planned for me, I will distribute the drives to anyone and everyone. I honestly don't even plan to load anything on them, I figure the threat will be enough. Now I just have to find a box of drives.

 

That was a good idea that turned into a winner.

I got 50 CD's for $6. I burned the pictures on about 10 of the CD's and took the whole spindle into her office this morning. I tossed her a couple of them and told her that she was looking at my insurance policy, and all 50 CD's would be available "for distribution" at our meeting on Thursday. She accused me of extortion. I think that's a nasty word, I prefer blackmail.

I also told her that I had a plan B that could be implemented if necessary. I didn't tell her what it was. That plan involves having all the pictures on a flash drive. During the dinner portion of this all day meeting, we historically flash pictures of our people and their families, or doing their favorite activities, or whatever. Sort of a 'get to know you' exercise. The pics run in a loop, all through dinner. If needed, I'll put the flash drive in the laptop running the slide show, and insert a slide show of my own.
