I feel somewhat clever about the title of this comic, clever enough to call it out like this.
Today's comic is a mostly true story about walking to lunch one day. In reality the underwear is seldom actually backwards. One typically realizes their underwear is backwards while putting on pants. Some underwear styles permit this as a possibility more than others. For instance, consider the g-string.
G-strings are weird; I don't even know why g's wear them, it doesn't seem gangster at all.
