His Trademark

While eating dinner the other night, Mo did something that made me laugh right out loud..... I saw him grab 2 pieces of bread, he buttered them, took one bite out of each piece, and sit them back on his plate.
I said, "Why did you take a bite out of each piece of bread?"
To which he replied, "It's my trademark." Like that was going to be a satisfactory answer for me.
I said, "What do you mean, your trademark?"
"Well, all growing up I used to do that to stop my brothers from eating my food when I turned my back. Doing this would discourage them from stealing my food."
I'm sure I would have been more surprised by this answer had I not ever witnessed what happens at mealtime at their house with 4 other brothers.
I guess it's a good thing to have a trademark. I'm trying to come up with my own. Any ideas? Or what are your own trademarks?
