Yes.... he did have long hair at one point during his eight months, but did anyone notice how long? I don't think it is possible to grow hair that long in 8 months. I do have to say this..... Harland Williams is the funniest guy EVER.
Actually, as a matter of act, his hair actually does grow. I used to watch this movie like every single day. When he starts to go crazy hits the sleeping chamber that Bill Overbeck is in, notice that his hair is long and he has a beard.
