WATCH: Samberg, Sandler & Fallon's Father's Day Song

Adam Sandler may have stopped by "Late Night with Jimmy Fallon" Friday to talk about his new movie "That's My Boy," but he ended up doing a little more than an interview.

See, with Father's Day on Sunday, Sandler was feeling a little emotional. He ended up breaking out in song, and with a surprise appearance by Andy Samberg, Fallon couldn't help but hop in too.

So if you're still trying to figure out what to get dad this Sunday, think about the gift of song.
