Or something!? Yeah, we watched it religiously when I was a kid. As I recall, he tripped over the ottoman upon entering his house in the first season or two, and then they had him smoothly dodging it when the opening title sequence was modified (I think they also hipped up the rhythm of the musical theme, as they did on many other shows at that time). There was also a rarer version of his entrance where he dodged the ottoman, but tripped on the carpet.
