A married couple has twins. They decide to name the twins after their fathers. The Arab man's father was named Amal, and his Mexican wife's father's name was Juan. To celebrate the twins' tenth birthday, they go to an amusement park. While standing in line for a funnel cake, the parents realize their sons are nowhere to be seen. They search around, but to no avail. Finally, they run to park security.
"You've got to help us," the wife says. "We've lost our sons!"
"Okay just calm down, ma'am," says the security guard. "We'll find them. Do you have a picture of them?"
"Yes, sir, right here," she says, and hands him a picture of Juan.
"Do you have a picture of the other boy, ma'am?"
"Well, they're identical twins. If you've seen Juan, you've seen Amal."
