Uhhhh.... I challenge you to get even *ONE* 300 lb fat guy into one of those teeny-weeny little seats.
I kind of have a feeling that they must limit everyone under the age of .... whatever.... from riding on it..
Or maybe it's everyone over 100 lbs... Maybe in the case of any discrepancies the carnival 'guess-your-weight' guy comes over to settle things...
"HEY YOU! Fat kid! What are you doing trying to sneak onto this ride!!! Why... You must be AT LEAST 105lbs! Don't try and trick me! I'm the Guess-Your-Weight guy! I KNOW YOUR WEIGHT!! MWAUAHAHAHAH..."
