From 'The Simpsons:
Saleswoman: This is our little hooker line. All the girls your age are wearing it, except the freakishly unpopular.
Lisa: But I'm 8 years old !
Saleswoman: So is your look.

From Local 6 WKMG:

Brockton High School has banned T-shirts with Sesame Street characters. But these are no regular pictures of Bert and Ernies. On some, Oscar the Grouch emerges from his garbage can, wielding a 9 mm handgun. On others, Bert and Ernie are standing in a gang posture, armed with automatic weapons. "We were amazed," said the school's principal, Susan Szachowicz. "You focus on the Sesame Street character. But the more we looked at it, the more we saw the things in it, the guns, the gang stuff." There have only been a few shirts at school, but officials said students are being told to stop to stop wearing them because of the pro-gang message.
