I'll second that. My son (aged about ?6 at the time) kept trying to attract my attention during takeoff... Once I realised he was serious and listened, he told me the fuel cap on his side was missing (PA28, so very obvious). Quick circuit to land, no obvious fuel loss...
ATC recovered it from the threshold - it had been sitting on the wing next to the tank during taxy.
