How do you surprise the people you love on their wedding day? Sure, there are gifts and cards, or maybe a well-timed and funny toast. But these guests decided to give one bride and groom the surprise of a lifetime by organizing a flash mob. The guests belt out the Beatles' "All You Need Is Love" and The Dixie Cups' "Going to the Chapel of Love" to serenade the happy couple. The bride had to fight back tears as all 170 guests joined in to make this day even more special.
