The humble t-shirt. Practical item of clothing? Barrier between nipples and cold air? Or a blank canvas for stupid humor? It’s more like all of the above. While these comedic tees lack the insane specificity of «Facebook shirts,» they definitely pack a punch, or can at least inspire a weary groan – especially when used in a funny context. Example: A man clutches his wife’s hand as she’s in the delivery room – wearing a shirt that simply reads «I did this.» Simple. Funny. Effective. Much like the rest of the novelty tees in this gallery.
