I did watch a PA28 do turns around a tiedown once because the PIC
didn't untie the left wing before trying to taxi out.

I once watched a rental 172 return from an apparently uneventful flight with
the rudder lock still attached to the rudder. Take-home lesson: Some folks
fly flat-footed.

Also, at least twice I have ran down and stopped planes on the taxiway with
flags flying from left-on pitot covers. Take-home lesson: One good reason
to put flags on them is so someone else can save your bacon after you do a
crappy preflight.
