how do you fall off a bike while cycling on a straight road

went to pengerang with the tos gang again today...and yes...clownish adrian fell off from his bike on the ride back to the jetty...

all i could remember was that i was doing a routine adjustment of my ass to relieve the numbness around the LP/ass region and next thing i know i was in push up position on the ground...

zhen de shi ta ma de suay...

scraped my knees and palms...thank god i didnt wreck the bike...many thanks to CheeBeng for helping me put back the bike's chain link which came off during the fall...

anyhows...here is the highlight of the day...
