On his front porch, Henry removes a shoe to have Charlotte tickle his bare foot. No sock. Ray summons them to Junk N Stuff. Presumably they go straight there. Once there, Henry is knocked off his feet. One shoe comes off, showing him wearing bold American flag socks. He's summoned home for dinner, and from dinner he returns directly to the Man Cave and is knocked unconscious. Laying on the floor, his ankles are bare, which is to say his is once again without socks.
In both parts one and two, Henry is shown wearing wide-waistband underwear. In the last scene of part one, Henry awakens and finds beige underwear on the floor of his bedroom. If Henry regularly wears wide-waistband underpants, who's slim-waistband beige undies did he hold up and examine. His own (simply a different brand)? Piper's or his mother's (dropped from the laundry)? A female guest (Bianca?) who might have visited through his window in the night? Is this to be suggestive of Henry becoming sexually active or of "going commando" under his PJs? It raises questions that go unanswered.
