This clip is from We Got Married's couple: Marco and Son Dambi. Marco is from Argentina, which is why he's singing to her in Spanish. This couple isn't the most popular one but this surely made me crack up xD

I almost pissed myself laughing xD He's so cute yet so funny, and this song, my god, I remember I used to sing it when I was in primary school O_O (in case you didn't know, I'm from Uruguay so yeah, we speak Spanish here).
