Funny enough, Lia and Roman aren't the only Anthonys to catch the attention of social media, because their father's name had people blown away.

As it turns out, their father is "Anthony Anthony." And, wait for it, his brother is: Anthony Anthony Jr. An instant classic.

Roman Anthony’s dad being Anthony Anthony isn’t discussed enough. What a name.
