The Third Wheel(2004)

When Stanley met Diana, he hadn't been on a date in over three years. She was easily the most appealing woman he'd ever seen: smart, successful, gorgeous--and newly single. For months now, he's been writing down the perfect way to ask her out, and imagining the perfect date. Much to his surprise, when he finally summons the nerve to ask her out, she says "yes." When the big night finally comes, everything that can go wrong on a date does--thanks to the constant interruptions of an uninvited stranger--the third wheel. But what starts out as an annoyance, could turn into something that surprises them all.
