As far as best man's speeches go, singer-songwriter Daniel Buccheri's takes the (wedding) cake. Instead of the usual toast, the brother of the groom sang his speech to a number of popular tunes like Sam Smith's "Stay With Me," The Police's "Every Breath You Take," and even R. Kelly's "Ignition." He alternated between gentle brotherly mockery and sincere love—a touching surprise for his older brother Adrian and his new wife.

By the end of the song, however, Buccheri turned a bit serious and sang about how much he appreciated everything his brother has done for him and how he, whether the older Buccheri realized it or not, has always looked up to him. The video will make you laugh at some parts, but anyone who watches it will have shed a tear or two by the end!
