They don't mention socks though. You just can't go wrong with socks.
andimspent is basically spamming, the blog is a joke, but that's actually a pretty good suggestion.
I'm not a father (and there are many children who are thankful for that) but out of the items you can get for a guy that are the wrong size, or just hideously ugly (ahem...ties), socks work out great as they are one size fits all and, unless you are Jimmy Buffet, they are always needed.
Whatever happened to the classic TV show routine where a guy is wearing two different socks, someone comments about them, and he says he has another pair just like them.
