I've gone a little crazy on my attack against Nick Jr airing vulgar comedy shows called "NickMom" on what was supposed to be a 24 hr preschool channel. It comes on at 7pm!! One min we are watching Dora, the next min there is some crazy broad talking about her vagina and sex.
It was nice to see so many other parents, including friends of mine, that also agree that NickMom is inappropriate for Nick Jr. 
I first went to Nick Jr and complained and by reading other posts I found out a few things. For one Nick Jr and Viacom have not responded to any of their parental viewers' complaints.  Two, parents are now trying to get the companies sponsoring NickMom to pull their advertising.  There is a facebook page that was started just for this.  http://www.facebook.com/#!/CancelNickMom
I loved the 24/7 preschool on tv.  I am not a perfect parent and I admit when my stinker wakes up at night I throw on some Nick Jr to get him back to sleep.  Sure I could throw in a DVD, but I liked the fact Nick Jr was educational and I could depend on them.
