I <3 Halloween

When else is the following perfectly acceptable?

1. A woman at Target in a poodle skirt, striped shirt, and a "visitor" tag.
2. A girl dressed like a slutty cowboy. (Okay...so you can see this one pretty frequently if you're at a club, bar, high school or retirement home.)
3. A guy dressed like a pirate, driving a Jeep Cherokee with a black ribbon sticker that says, "Support Lap Dancing."
