The most recent episode of Jackie Kashian's The Dork Forest was all about recreational salsa dancing.
My thought process while listening to it went something like this:
1. Sweaty dancing in painful shoes does not sound fun.
2. Wait. Now I have been convinced that dancing would be a good work out.
3. I wish I had the guts to take swing dancing classes. But I've seen the beginning of Strictly Ballroom too many times to go through that.
4. ... maybe if I dragged someone along with me to classes?
To sum up: Talk of SALSA dancing makes me want to take SWING dancing classes.
Obviously, the dance-related portion of my brain has a wire or two crossed.
(Also: there is very low probability that I'll even remember this urge to take swing classes ever existed in 24 hours.)
