BBC sketch comedy show The Wrong Door put together a handy PSA for those who tend to get a bit too excited during co-ed Wii play. Oh, it's painfully obvious, but I saw Crecente type "haha" earlier today after having watched the clip. Maybe you'll type "haha" too? If not, maybe the crude Wii Sports tennis and Mii renderings will elicit at least a "heh."
Thanks for the heads up, Robert!
