A Twin Can't Have Twins...
I have a set of 10 month old twin boys. I am always asked if twins run in the family. When I say I am a twin, I get "twins always skip a generation" or "twins can't have twins". I had a lady call me a liar about being a twin. Wow. Or when I am asked if they are twins, I say nope, it was buy one get one free at the hospital.
