I don't know...my Dad turned 59 this year and I gave him all kinds of crap about it :)

Exactly. I think it was more of a poke at his being 60 than anything else. I can imagine people getting this game as an "Over the Hill" gag gift. Of course, unlike normal gag gifts, this one is actually something you'll use everyday.
