Media Monday's: YouTube for the Pre-School generation

So my four-year-old nephew discovered YouTube about a month or so ago. Ever since then, he's been taken with watching cartoon clips, or videos of fire trucks and police cars. Normal kid stuff.

But he's also discovered some pretty hot-and-heavy soft core action. Nothing too graphic, but apparently enough to put some filters on YouTube. Just shows my sister what happens when she turns her back on her kids just for a moment.

He's also gotten fairly clever, as evidenced by this exchange we had last weekend:
Him: "Uncle, I want to figure out why girls go swimming...so can you type 'Girls Swimming' into the computer for me?"
Me: "You know your mom doesn't want you looking at girls on the computer.
Him: "Well, can you just do Thomas the Train then."

He's also tried to get me to find videos of mermaids. And not the animated ones that sing with crabs.
