Wait for it

A young boy in a red and white "I Love Michelle Obama" shirt performs a split on a polka-dotted stage while a group of performers in military-style uniforms dance behind him under bright stage lights. The scene cuts to three children sitting on red stools, each holding a microphone and singing, followed by a title card for "Lip Sync Battle Shorties," then to a man in a black and yellow jacket who smiles and points at the camera before peeking out from behind a door.
