There's also a comma missing after the contraction for "Come on." Which may be worse.
If it weren't for that first missing comma, we might think this was a hilarious gay man's truck; unfortunately (or for our purposes, fortunately), this is clearly a pretty straight-up error. We don't know why it's so fun to see someone trying to be tough get deflated, but it definitely is. Not that the font was really helping his badass phrase much, either. Hopefully, no one points out to him that the large cat in his window (is that a saber-toothed bobcat?) looks like it has a handlebar mustache that belongs in a leather bar in San Francisco. We also hope neither he nor his friends have the Internet, so he can continue to drive around feeling macho.
