I know because they're wearing bow ties. Shalom! I'm Larry David. You may know me because I was a writer for Saturday Night Live and Seinfeld, or you may watch my show, Curb Your Enthusiasm. Aside from being a great comedic writer, I have the rare talent of being able to identify Muslims with nothing more than a glance. Here's my secret: men who wear bow ties are Muslims. You may think that members of the Nation of Islam are the only Muslims that wear bow ties, but they aren't. I have found that almost anyone who wears a bow tie is a Muslim. There are a few exceptions to this and not all Muslims wear bow ties. Terrorists, for example, don't wear bow ties in public places because they would be identified right away and arrested.
