Place it after the introduction of the sister and before the reaction beat, so the joke lands as a reveal. Follow it with a record scratch for the freeze moment, then a laugh track to close the sitcom rhythm.

This is a 12-second clip of Barney Stinson singing a Christmas-style jingle about Ted Mosby's younger sister Heather, delivered with eager, flirtatious energy. It feels cheeky, awkward and funny, like a festive tease aimed at an overprotective friend. It comes from How I Met Your Mother, in the 2008 episode Little Minnesota.
