Can recommend. I bought a huge bag of these exact babies and spent a Saturday morning hiding them throughout my entire office building, including my own work area (for plausible deniability). People were finding them for years. More than one co-worker would re-hide them, so the babies migrated constantly.
Nobody knew I started the whole thing they blamed our HR director, who was on holiday that weekend and had an alibi. The mystery kept people intrigued.
I used to have a bag of plastic ants, and I would leave a few on computer keyboards when they went out for lunch. Then I'd forget that I did it, until I'd be working at my desk, and hear a shriek from out there, and remember, and smile.
used to put googly eyes everywhere. at work, at my parents and grandparents place, anywhere I went. my grandma didn't know she had those in the handles on her walker for a year.
We did googly eyes too for April Fools' Day one year and they are still so many places, including at work and in our cars 
Jennifer:Baby #184 found. Asshole still hasn't got my message yet!
Imagine you have to make that living space baby proof after hiding at least 200 pieces of small plastic pieces in there.. (・_・;)
Willy Johnson’s cortisol levels are so high the poor dude can’t sport a Woodrow.
An old roommate did this but with pennies. I was finding them in my pockets and socks for years.
Reminds me of the duck guy (James Veitch, not /u/fuckswithducks) (unless they're the same person of course)
...gimme five bags of that, please.
