Why is Valentine's Day funny? Because couples try to get lucky with one another. Why? We thought it was guaranteed sex. Single people can sit back, relax and just see what happens. Forget Wednesday. Valentine's Day is the true hump day, and single people can explore their options. Unlike couples, singles aren't stuck with their valentine. Luckily for singles, everyone feels a little lonely on Valentine's Day, so getting laid is like Cupid shooting horny fish in barrel.
