Okay, you knew this was coming, didn't you?

Who gets to leave the obligatory "I'll show up if Amy does" comment??
(winks)
Seriously, this (the bike thing) is like the 'bad naked' on Seinfeld. And it involved a bike too.

People who show up to "Let's All Get Naked!" events are typically the last people you'd ever want to see,

Every year on the weekend of (or nearest) the summer solstice,
the Seattle neighborhood of Fremont has a street fair and, as part
of the fair, there's the Solstice Parade. For many years, a group of
naked cyclists has ridden before the main part of the parade. There used to be only a hundred or so, and they would occasionally get hassled by the cops, but in the past few years their numbers have greatly increased to 400-500 or more, and the cops have left them alone. While naked, most of them have body paint on. Some are very creatively painted; others not so much. The ratio of men to women used to be very high but a lot more women have started participating so I'd say it's almost 50/50 now.

While, in line with your comment above, there are certainly a lot of cyclists that don't look good naked, but there are also a fair number with good bodies.

Well I stopped going to the beach when the nice people started throwing water on me and tried to push me into the water. ;-)

"People who show up to "Let's All Get Naked!" events are typically the last people you'd ever want to see..."

This makes me think of two things: Gym locker rooms,and swingers.

Perhaps my personal health club experience is very limited, but I've observed that the individuals who are least reluctant to prance around the locker room naked are the biggest, floppiest, bushiest AARP members.

As for the swingers, I don't know many...BUT the ones I DO know (more than one couple) are always Boomers who've done a lot of tanning but forgot to renew the subscription to InStyle. I'm sure they exist, but I've never met a hot swinger couple. (Disclaimer: We don't Swing, so it's not like I'm out there.)

Why would anyone want a tiny bicycle seat practically shoving itself up his or her ugly, naked ass? (Of course, some people might be into that sort of thing).

Not to mention the possibility of the seat changing from black to brown during the event.

A pirate sold me a car today. Turned out to be a lemon with a cow in the back seat. I went back to the dealership and hit him with a telephone pole.

We have a huge naked bike ride here in Portland every year. And you're right. 90% of those people I'd never want to see naked!

As Jeff Foxworthy once observed, "The laws against public nudity are not intended to prevent sex. They are intended to prevent nausea!"

"Bad naked. Good naked is naked for boyfriend. Bad naked is naked for everybody else's boyfriend"

I almost get the feeling that some of the people who make a point of going naked at events like this may be almost conceptually regarding nakedness as being for 'special events', and thus may actually be concealing a conceptually opposite position, i.e. that they are ordinarily squeamish and overly-'Victorian' about their own nakedness. E.g. "It's funny and exciting and novel because, tee-hee, deep down I am in reality uncomfortable with my own sexuality". (Not that I blame people, it's difficult not to be like that in puritanical Western culture.)

But perhaps I'm just over-analyzing.

"Why would anyone want a tiny bicycle seat practically shoving itself up his or her ugly, naked ass?"

As a cyclist, the idea of a sweaty naked butt crack striding a tiny bicycle seat is one of the most disgusting things I can imagine. Ugh. I would have to disinfect the seat and throw it away and buy a new one.
