The man in the gray t-shirt pulls little green men out of beard; too much drinking, I guess.
Green things someone pulls out of his beard are not necessarily little green men. To hover over one's beer bottle and Guinness glass pulling green things out of one's beard does not necessarily imply too much drinking.
Just because a man is pulling green things out of his beard doesn't mean he is pulling little green men out of his beard.
