What kind of Low Life S would put Vulgar crap in a children's Christmas video on youtube?

I was lookin to make a playlist for my grand kid's and the 10 yr. old was in the room w/. Iknow I should have previewed the full video (which I normally do) but at the very end is 10 sec. of profanity that I missed. My grandaughter is very smart and she just patted me on the shoulder and said "nice christmas song PaPa. I WOULD LIKE TO GET MY HANDS ON THESE MENTAL MIDGETS....How bout You???
