"Hey Steve, Boquisha was telling her girls you two went out on a date last Tuesday, is that true?"

"Hey baby, I saw you were online, thought you might be up for a little swim and a midnight lunch..."
"Sounds good, I love Denny's ranch dressing, do you have a wifebeater I can borrow? I lost my swimsuit.."
