Krusty sponsors a 'class clown' competition at Springfield Elementary, pitting Bart against an unlikely competitor - Milhouse Van Houten! Also, sign up on Springfield's newest social networking site 'Bart Space.' Then, join Maggie and Moe as they attempt to solve several crimes at once - but will they save Hans Moleman in time? Make Bart a part of the action this December!
