this stick was made for walking

YIC has invested in a walking stick. As he tramps around New Zealand, he finds that walking with a heavy pack gives his knees gyp. Perhaps he is getting old (surely not! the readers cry). As he walks along, he finds that he is prone to whistle a tune to him, pass a few bon mots to no-one in particular, and chuckle to himself. He even twirls the stick absentmindedly as he walks. Soon he might be putting the stick on a shelf in a pub, commanding the nearest customer to not let him forget it, then promptly walking out of the establishment and leaving the said stick behind. Now who does that remind readers of? (hint - he is a close relative of YIC)
