Brandon Hopkins and his wife are currently expecting twins, and one of the babies is already showing how cool he or she is in the ultrasound.

After the baby’s uncle posted a photo of the ultrasound on Reddit showing the baby with a thumbs up, the picture quickly went viral. The photo was first posted by Hopkins on his Facebook page.

Ultrasounds are often one of the most joyous photos expectant parents can see, but this one is extra special because of its unique nature.

“My brother called me and said 'Your babies are famous!'" Hopkins told HLN.

The babies are due in January and the parents-to-be have yet to find out the sex.

According to Fox4kc, the baby has adopted the nickname “Fonzie Feetus” after the iconic Happy Days character ‘The Fonz.’

The ultrasound was taken last week and it will surely be a topic of conversation in the Hopkins family for years to come.

“I thought it was really cool," Hopkins told ABC News.
