Trix may be for kids, but kids shows are for adults as well. Many T.V. shows these days that are aimed at children also throw in some grown-up humor, attracting an audience with a wide age range. A show that comes to mind is "The Muppet Show" which appeals to kids of all ages. The kids show "Yo Gabba Gabba" has things for the kids, but features appearances by rock bands and famous comedians for the adults.
Lots of cartoons combine humor for the kids and adults. Nickelodeon's "The Ren and Stimpy Show" was chock full of gross out humor and that never gets old no matter what your age. Who can forget the "Rocky and Bullwinkle Show" and many of the "Looney Tunes" cartoons with Daffy Duck and Bugs Bunny. I still laugh out loud.
