Tuesday night, NBC aired the self-explanatory One Direction: The TV Special. Naturally, it featured the band’s members performing their songs and engaging in some behind the scenes antics. (Niall in tighty whities, anyone?)

Some highlights: Niall playing shirtless ping pong and air guitar at the same time(just go with it). Liam quizzing the other members while riding a roller coaster. Zayn, who doesn’t like roller coasters, opting out. (In this segment, it was revealed that Louis’s favorite movie is Grease.) They all also travel to Christ the Redeemer in Rio de Janeiro smuggled in the back of a bread van.

Oh, and during a section about the band’s recording process, Niall sang and danced around in his underwear—because if nothing else, these guys seem to know their audience.
