The Hulk is Recovered

So today I'm pulling into the parking lot at Jackson's school and out of nowhere he says "I found my hulk toothbrush in the trash so I cleaned him off with water."

Er...Wait... what?

"My toothbrush, the purple one with The Hulk on it, it was in the garbage! I took it out and I cleaned it off with some water."

And off he runs into school.

So on the way to work I think about this.  How long was The Hulk in the trash?  Did Jackson brush his teeth with it after he cleaned it off with some water? And all I came up with is this: kids are gross.
