About T-Shirt Design
One look at I Find Your Lack Of Math Disturbing T-Shirt and you pretty much know what kind of sense of humor it has. It fits really well with science and nerd humor, but you do not have to be obsessed with that stuff to enjoy the joke.
This is an easy gift idea for birthdays, work, or someone who is hard to shop for but loves funny shirts. It has the relaxed feel people usually want from novelty shirts without getting too complicated. The whole point is to get a laugh, and the shirt does that without making things complicated.
