I would find it amusing except that I was guilty of the same thing on my first trip with my Bike Friday.
I had taken it along on a business trip to London and rode out to Oxford after the meetings were over. The next morning when I was assembling the bike I was distracted a little by a homeless man who kept wandering over but got the bike together and set off for Windsor Castle. But on the way I noticed that it was unusually easy to lift the rear wheel when braking. That caused me to check out the bike a little more closely and I realized that the front fork was flipped around thereby making the wheelbase significantly shorter.
