I have a lighter/pencil sharpener.

I have no idea who decided this combination made sense.

A digital audio recorder. Used it in the last 30 minutes of my Biology lecture when tetris suddenly became more interesting than the course into. Got to listen to it later when I cared, don't remember getting it though.

a little stand with rotatable arms with clips on the end of them...Can't remember where or how it came into my possession, but its super cool and very handy. I solder circuit boards from time to time, like yesterday when i fixed my keychain Dongle for my car alarm...and this little wee 'extra fingers' gadget was perfect yet again. I am certain I have had it over 25 years...just not certain when or where i got it.
