Hi,
not dissing your mate in any way, but it's dead easy. Just put your bike on it's side and twist the (straight) handlebars by 170º so that they point almost straight up.
Next, fall in such a way as to impale the centre of your chest on the end of the bars.
There! Done! Easy peasy cheezy!
Agreed, it's a bit harder to improvise this while bicycling along, but I've had very special training - at the Retards School for Bicycling Idiots...
