White elephant in March – gift ideas?

My parents and I all have birthdays in March so we were going to do a white elephant as a gift exchange instead. I know it's kind of silly but any suggestions for gifts for parents?

I might get my own gift back but want to get something we'd all like. We're all developers actually so I thought it'd be funny to get something with that theme in mind, and I figured the HN community would be perfect to ask

"A white elephant gift exchange, Yankee swap or Dirty Santa is a party game where amusing and impractical gifts are exchanged during festivities. The goal of a white elephant gift exchange is to entertain party-goers rather than to gain a genuinely valuable or highly sought-after item."

If you guys don't already have a Raspberry Pi, it would be fun for all of you to set up a family home-server. Each of you can run their own services on it :)
