George Tesman's "Imagine That....Uh?

George says "just imagine" or "imagine that" and "uh" numerous times throughout the play. I believe George constantly says "just imagine" and "uh" because it shows that he is thinking and wondering of the possibilities that can occur. This shows that George is always in a dream state or dreaming of what he wants instead of going out and getting it. It seems like George doesn't want to face his reality and lives his life in his studies and research instead of reality. Just imagine if George could stop imagining and get into reality...uh?
