From bad chompers to bad hair. Watch out for the NSFW expletives.
I saw that the other day, half forgot it, then played it again today and laughed even more. I see some commenters over at YouTube think it's fake -- I disagree -- and others feel very sorry for the young woman -- and I disagree with that too. The line "you'll look back on this and laugh" is spoken in the clip, and it was never more true. But if it's not -- if the bride never looks back and laughs -- I feel very sorry for the groom.
