anyone doing a surprise

first dance?
we are thinking about it ---- but do you need to have a talent for dancing and moves or is it PRACTICE PRACTICE PRACTICE?
Will it look stupid? I've never seen it in real life but when I see it on youtube I'm like 'How great is that' and i was telling my dad and sister and they're like SHHH don't tell us - just do it.
(& the only reason why I bought it up is bc I wanted to see what he would say since there are going to be a bunch of people he does business with at the wedding so I didnt want him to be embarassed or antyhing LOL & i Just wanted to feel him out)
