Why are bart, Lisa and Maggie blonde?
Are they blonde?, they don't have hair lines like everyone else, but they style it so it can't just be head....
Are the aliens that have fooled everyone into believing they are the children of Homer and Marge.
And I don't think I'm breaking new ground with this, but I'm not a Simpsons fan so I don't discuss it enough to care about this until I'm high
