Oscar Wilde famously quipped, "Be yourself—everyone else is already taken."
Identical twins are born with a built-in collaborator for identity theft, and some take advantage for the situation for pranks and hijinks. Having a doppelganger isn't always fun, however, as identical twins are sometimes inconvenienced by cases of mistaken identity and are constantly accused of cheating even when they're not.
In a thread on Reddit, twins shared the awkward moments that arise from having exact lookalikes, as if having one You wasn't already awkward enough.
My twin brother recommended a restaurant to me. Said that he and his wife went there all the time, good food, really friendly staff...
So I took my wife there. Food was as advertised, but the service... somewhere between cold and openly hostile. Like they resented our presence. I was puzzled by the contrast between what I'd heard and what I saw.
Suddenly from the front of the restaurant, explosion of laughter, much rapid talking, suddenly the waitress is there, smiling and all... just as my brother and his wife walk around the corner.
They thought my brother was cheating on his wife with some blonde... Yeah, it's funny now. -BobMacActual
