If two people ran into each other both wearing this shirt, would they implode?

Nope. regardless of the perception, the quote would fit no matter who wore the shirt, or if many wore it. now if one had a shirt that read "u > i" then it could lead to catastrophic implications. :D

OK, when I start thinking about the mathematical equation to solve this dilemma, I think it is time to move on...

did you start assigning number values to "u" and "i"

same here..
