Entering the busiest roundabout in my area I got into the saddle from a standstill and managed to hook the rear of my rather baggy jersey onto the nose of the saddle.
This was not just a simple snag but a full-on, forcible pull which resulted in me being throttled at the front as the neck was pulled rearwards.
No matter how hard I struggled would anything come free and I couldn't even sit down due to the tension. All this against a background of an extremely busy roundabout and me trying to turn right.
Finally I woke up to the fact that if I unzipped the jersey at the front I would be able to breathe again, not immediately realizing that after doing so and sitting down the rear of my jersey would try to join the part of the jersey still trapped on the saddle I was now sitting on. And a very fetching plunging rear neckline it was too.
I stopped shortly afterwards to get dressed again and consoled myself with the thought that whilst I must have looked a complete wally, at least I had managed to do all the required hand signals in my manoeuvres.
