In November 2001 I went to Britain and saw a London go-go dancer fake it as an equetrian. Unfortunately she failed. But I loved the idea. Now it’s on TLC. Kudos. The first episode not only featured Gen from Trading Spaces, but was an outstanding success for the poor slob involved. I cheered when he won! Hoo-ra!
So … we’re talking about baseball? Or orgasms?
Or something?
Go-go dancing. Clearly. 
There is a new show where someone has a certain short amount of time to learn a job they don’t know. Then they have to try to fool people who really do, do the job.
Yeah, my reaction to the OP was a “WTF-F?” and about six or seven of these things:
What is an equetrian?
I’ve got this weird mental image of Nancy Sinatra in a shaggy dress and white vinyl go-go boots doing the 'Frug with two guys in a horse costume. Again, what’s a “equetrian”?
Heheheh. I thought it might be “equestrian” also, but I dunno.
Did you travel to London for the express purpose of seeing a go-go dancer fake it as an equetrian?
Yeah, I meant “equestrian”. You guys are so cute!
Satisfying Andy Licious, naw. We saw it in the down time between sight seeing and drinking.
