What would you do? Or think?

You and the hot, leggy blonde from the office go out for a few drinks after work at the local bar. The conversation and the liquor flows freely. A few drinks turn into a few more, and before you know it, you're both feeling randy. You've been kinda sorta seeing someone else but you decide it doesn't matter since she is in a different zip code. It's almost closing time and you decide to invite her to your place to continue the fun. When you arrive, you immediately lead her to your bedroom. Not wasting any time, you strip each other down and start going at it. Afterwards, you're both lying under the sheets. You start mumbling about how much fun that was. Your head is spinning, your speech slurred, and on the verge of passing out you say, "Goodnight Rachel."

The next day at work, you mention the previous night. She gives you a weird look. You ask about the strange look. She proceeds to give you the low-down. As you were passing out, you said goodnight to her, but her name is Angela, not Rachel. Oops.
