Little Bear to Porn Movies,grrrrrrrrr!

My son woke up and since he did not go back to sleep,I turned on the tv so he can just watch some cartoons.He was watching Little Bear and was really enjoying it.At first I heard little bear calling his mom and then it stopped so I checked what happened and to my surprise I saw the show changed from little bear to a porn movie.At first I thought I accidentally changed the channel since the remote was under my feet but when I checked it,it was still the same channel.So I changed the channel and when I checked again a minute later,it was only showing black screen.I guess who ever is in charge of the cable or the satelite messed up.I just hope and Pray that it won't happen again because my son is too young to be watching those kind of movies.
