the death of a Wiimote

Last night my coworker's girlfriend had a graduation/leaving the US forever party to which I was invited. The party was pretty cool. She is Japanese and there were lots of Japanese people in attendance. Actually, about 90% of the people there spoke Japanese, so that's pretty much all I heard all night except for a little English here and there and Cantonese. My other coworker was also there and he brought his big ass TV and his Wii and three Wiimotes for the party. I brought my Wiimote to make 4 so we could play some tennis. It was a blast, and everyone enjoyed playing Wii Sports and Rayman. People were playing pretty much the entire night except when they turned off the TV to get people to stop playing so they could clear room for some other (boring) games like Twister. It wasn't long after that the Wii was back on for some drunken Rayman action. It wasn't until toward the end of the party while someone was playing boxing that I noticed one of their gloves wasn't moving and was stuck pointing in the air. After inspecting the remote, I realized it was my Wiimote. I hadn't really played much that night since I was too busy socalizing, so I have no idea when or how it happened, but at some point during the night, my Wiimote's motion sensor died. So now my Wiimote can only point and click. Well basically it can do everything normally, except it doesn't register any motion, so I can't play anything now. I bought the warranty for the Wii so I'm hoping I can just take the dead Wiimote to Best Buy and get it replaced. If that doesn't work, I guess I can open up one of the 4 brand new Wiimotes I bought from Wal-Mart (all of which I still have btw), take the new one, put the bad one in the package, and try and return it to Wal-Mart saying it was broken. It's all very sad, as I was wanting to play some bowling today until I remembered I can't actually throw the ball anymore. :'(

I guess I can at least be thankful nothing like this happened..
