For those that have/ had twins, what’s your funniest “wait..:you’re a twin??” story

It was three weeks into the school year. It was lunch block and I was taking attendance. For the first month or so, I always do the “If I call your full name, say ‘here’” routine.

I called out one student to see if he was present. Then I called another student with the same last name.

I paused and said, “Wait a minute, why do you two have the same last name?”

Then I looked at both of them, noticing they look the exact same. Then I said, “Are you two twins??”
