The Wool in his Pants

A few days ago, while Boober was at home with me due to an illness (his, not mine) and working away in the office at one of his "creations" (which always come out looking like tamed chaos) he walked up to my chair and asked: "You know why I have wool in my pants?". I said, "No Boober, why?". "Because it makes me feel comfy".
