When I was in high school we hosted the annual Bais Yaakov Convention. As part of the decoration some girls built a 7 foot “girl” with an arm that waved, who we nicknamed Bertha. (Sounds fancier than it was, it was really some painted plywood and simple engineering.) On Rosh Chodesh Adar a group of boys from the local yeshiva stole our Bertha! They took pictures of themselves together with her, blacked out their faces and hung copies all over our city. The high school girls were really upset, especially the group that worked hard to make her!
Rumour has it that Bertha is still sitting in the yeshiva dorm, smiling and waving to those who enter.
