A woman buys a leather skirt on sale, and it's just a wee bit too tight, but she figures--what the hell!--it's a really good deal. The first time she wears it, she goes down to the bus stop to go downtown.

When the bus gets there, the skirt is too tight and she can't quite step up onto the platform.

So, she reaches behind and pulls the zipper down a litttle. Still can't step up.

So, she pulls the zip down a little further. No good: she still can't do it. OK, she reaches behind and pulls that zipper down all the way, but it's not working.

Just then, this cowboy standing behind her in line, grabs her around the waist and lifts her onto the bus platform. She is incensed! "How DARE you put your hands on me?!?!" "Wal, ma'am, " drawls the cowpoke, " I wasn't rightly sure the first two times. But oncet ya pulled mah zipper down all the way, I figured we wuz FRIENDS!"
