Whenever I see stacked boxes, whether they are neat or poorly stacked, I think of Teris. Sometimes, when looking at the fish tanks at Walmart (or other such pet stores), I look closely at the fish and think Which one of these closely resemble a Cheep-Cheep?
When I'm at work, I have to warm up a cinnamon roll. The microwave is under a part of the counter that I duck behind in order to get to it. I often hear the Mario pipe sound as I duck/come back when heating things up.
My parents have these mushrooms that grow near an old stump in their yard, and these mushrooms have a color scheme similar to that of Goombas. When they tell me to just stomp on the mushrooms, I hear myself getting points in my head.
I have looked at the clouds and thought I saw Mario and Yoshi flying through them once (I was fairly young, however).
Whenever I buy something I really want (most recently, Mario Kart Wii) then the Zelda You go the item! sound goes through my head.
After using the computer for extened amounts of time, if I want to go 'undo' something, I'll say Wait a minute, Undo that last statement.
I have more, but I think that about covers it. Do I have a problem? XD
