Dance costume Puns

I am asking my girlfriend to the Homecoming dance in about a month, and it's been a running joke to be as cheesy as possible in our relationship. For this year, I was brainstorming and I saw a pirate costume in my attic. So I am going to take her on a date to a nearby lake, and then my friends are going to row up in a canoe dressed as pirates. They are going to somehow give her a treasure chest for safekeeping (I haven't really thought all of this through yet), and inside will hopefully be one of your puns asking her. Please help arrrr/puns!
