At the National DanceOff, when ChaCha is meeting the gang, the T-Birds and Pink Ladies are in a line. In the close-up shots, Putzie is alongside the girls, with plenty of room between him and ChaCha. But in the longer shots, he is squeezed out and behind one of the girls, with only his head poking into shot over a shoulder. Look at his face, he is clearly a bit embarassed.
