Will Reeve, a reporter for ABC and the son of legendary “Superman” actor Christopher Reeve, made a guest appearance on “Good Morning America” Tuesday morning to give input about pharmacies using drones to deliver prescriptions.

But his interview has gone viral for a different reason.

While Reeve was dressed formally on his upper half, wearing a button-down shirt and a sports coat, he was not wearing pants during the TV segment, Gizmodo reports.

After the interview, Reeve took to Twitter to poke fun at his mistake and clarify that he will definitely be wearing pants to work at all times from now on.

Reeve also responded to Detroit News film critic Adam Graham — who was the first to post the viral image of Reeve’s mistake on Twitter — clarifying that he was not in his underwear but simply wearing shorts, Decider reported.
