Cannon and smiley faces

anyone ever look at a cannon printers’ cartridge holder? its weird looking! On the tab you push to open it, it has two dots(for grip maybe) pertruding(sp?) from the plastic.then smack dab under neath those two dots is a slash a curved one. it looks like a smiley face! anyone else see this humoros(sp?) face on the cartridge? is it made purpousely or not?
