Look princess, if someone watches a kids show, they like it. And they either like it for the animation, the characters, or both. It's only bad if they watch research of it or find it arousing or god forbid anything along the lines of loveuality.

1. Find the nearest bridge.
2. Stand on the rail, with only underwear on.
3. Jump off while reciting Winter Wrap Up quietly.
4. Congratulations, you have cleaned the dead leaves off the gene pool.
