We do a brisk office black market in the good post-it notes, the good pens, the good highlighters, the good legal pads...... If you get a stash of the decent quality ones, you can run the place. As such, most presents within the workplace include some of them, if you like the person.
My worst isn't actually bad, it's probably my favorite present ever, but it's weird. Back in my early days of working in pharmacy, drug companies could still give away promotional items like pens, clipboards, notepads, sticky notes, etc. Drug company pens were highly coveted, especially. Alas, this has now been banned (made illegal, I think?) in an attempt to lower monopolies and control drug prices (spoiler alert: failed experiment, bring back the pens). For my 18th birthday, a few friends did a series of trades among the hospital staff and got me a Viagra pen. That's basically like someone getting you a car and they pick out a Ferrari. But people outside the industry are like....you're excited....about a penis pill pen? Why yes.
Someone stole it a few years later. I still mourn the loss.
