"He's too short, he's too... tall, he's... just not going to work"

This quote by Ed Wood is a humorous method of expressing the concept that somebody is not suitable for a particular task. It suggests that the individual in concern is either too short or too high to be ideal for the task, which no matter what their height is, they are not going to work. This might be interpreted as a metaphor for how often no matter how hard we attempt, we are not appropriate for particular tasks or functions. It could also be analyzed as a commentary on how society typically puts too much emphasis on physical attributes such as height, and how this can be a barrier to success. Eventually, this quote is a pointer that we should not be evaluated exclusively on our physical attributes, which we must be offered the chance to prove ourselves regardless of our height.
