Immediately after I finished this I thought of a better way to do the sequence. Also I'm not real happy with that last frame. I'm gonna try to redo the whole thing in the near future.
I thought for the REDO I could have him walking around in an amusement park. He sees signs on all the rides stating: MUST BE 40" TO RIDE. Each time he sees this sign he is saddened because he's too short.
Later he sees this sign at the hoochie coochie tent (my grandma told me they had hoochie coochie tents at the fairs when she was little) and it has a MUST BE 21 TO ENTER sign beside the tent flap. He jumps for joy and runs inside. I figure no tape-measuring would be necessary for that version.
