Wiiiiiiiiiiiiiiiiiiii! (gonads and strife)

Located a Wii for my dad for Xmas (mom wants to get it for him.) So, Wii-enthusiasts, I'm looking for some Wii game recommendations. Preferably, easy-to-understand party games. Some caveats:

My dad is 64 years old and does not know Mario from Mega Man. So, something like Super Smash Bros. is probably not his deal.

Same goes for anything that requires you to make a Mii, or whose primary attraction is friend codes and online play.

I'm thinking Boom Blox might be a good candidate, as an example. Any other suggestions?
