While Matthew does his bodybuilder pose he makes this guttural grunt. At first I thought that Matthew was pooping.. but Tony thinks it is his way of expressing extreme excitement. (Of course Tony thinks this because Matthew does this most often when Tony first gets home from work.) We are trying to capture Matthew's pose and grunt on video, but it is a spontaneous act that we cannot always predict. If we do capture it we will post it on a future blog. We refer to this expression as Matthew's hulk imitation. Perhaps we have been feeding him too much green guacamole.
