Gravity Falls is a new cartoon on Disney Channel. It's about two kids, Dipper and Mable, who go to their Gruncle Stan's place for the summer.
Dipper is a bit straight laced, and the critical thinker. He is usually trying to get Mable to focus on whatever thing it is they are doing.
Mable is a little spastic, and definitely an asymmetric thinker. Where Dipper is stumped in their problems, usually an idle comment by her gets them going again.
Gruncle Stan is a man of world experience, a bit of ill repute, and a shyster, but he means well. He's usually the comedic relief when he is around.
Gideon's Dad: Oh Stan, Come on in, we have coffee all the way from Columbia.
Stan: Wow Columbia? I went to prison there once.
It's got some spastic humor because it is a kid's cartoon show, but the humor is pretty clever a lot of the time as well. There's few other cartoon shows that could compete for your time at the moment.
