It seems a mistake at the printing press has caused quite a stir on the web. You see, several websites were making fun of Bert (of Sesame Street Fame) and Osama being pals. All of the original pictures were doctored. There are several theories on how the Bert/Osama picture wound up on the poster. One includes a printing press that got in a hurry, pulled one of the doctored photos from the web and didnt pay attention to what they were putting on the poster. There are several more that can be found all over the web. I found this site to be the most informative. Bert/Osama.
