"Is it Bernard?"

Have you ever been mistaken for someone else? Maybe it happens to other people more often, but it's never happened to me before, until yesterday.
So I was walking from my Folklore class to my Chemistry class and as I rounded a corner, this guy looks at me, stops, and says "Is it Bernard?" Realizing that he's talking to me, I stop and look at him. Then he repeats the question "Is it Bernard?" I give him a confused look wondering what he's talking about when I realize he's asking if I'm Bernard. I slowly say "No, it's Dan." But he just keeps on looking at me like he's still half-expecting to have a conversation with me as I turn and walk away.
I thought to myself, why would he think I looked like Bernard? Was I making some sort of strange expression with my face? Did my hair look like Bernards from being mashed down by my beanie? Was it the fact that I hadn't shaved for 4 days? Was it the way members of some secret organization identify each other? Or do I just amazingly resemble Bernard? I began to wonder myself if it wasn't really Bernard after all, but as I rounded the next corner, I recieved a friendly slap on the shoulder from a mission buddy who let me know that I really am who I think I am and not Bernard.

Bernardly,

Dan

P.S. I thought of some other closing lines like 'Bernarderiffic', 'Bernardtastic', 'Bernardfully', and 'With warm Bernards'.
