At work, our keys, radios, and rf guns are numbered so that they can keep track of who takes what (Canadian Tire). I always go for gun/radio/keys #9 (GaW main in melee and brawl).
My dad (police officer) used to have a fellow cop named Kirby (no joke, that was his actual first name).
Whenever someone says their name is Roy, melee Roy always pops into my head. If we're on the same team for something (sports, etc.), I'll sometimes start a team chant of "Roy's our boy!"
The song "why does love always feel like a Battlefield" (or something like that) plays all the time at work. Every time I hear that, I keep changing the lyrics in my head to "why do I always get gimped by Battlefield".
I sometimes initial things as "BY" at various places... including work. I also write my name as "Blue Yoshi" for some things as well (as in serious things where you're supposed to give your real name)
The movie Final Destination... enough said.
In my chem 11 class (like 4 years ago), my teacher made jokes about measurements (like "what's 10^-6 phones? A micro phone!" Or "what's 10^-12 surprises? Piko boo!" The first thing I thought of was "What's 10^-12 sneezes?" (I'll let you figure it out
) I never said it out loud... but now I wish I did
That's all I can think of for now...
