What to engrave onto leatherman? 60p giveaway inside

Hey guys.

I got my father a Leatherman Wave and a nice knife as a christmas present that I will give him in a few days.

I want to engrave something into one of those. I can't think of anything right now and "to father, from son" is just too bad.

I need something fun and creative but without showing too much love as this just isnt part of our relationship.
But he will keep those items forever and it should remind him of me.
I dont have any nicknames btw.

I opened 60p giveaway for my whitelisted people. all people participating will get onto whitelist
