A bunch of Litfisheh bachurim were going collecting by a rich chossid. After bringing a rayah from the migellah that mordechai was a litvak the chossid offered the bochur a few hundred dollars if he could bring a rayah that modcheh /mordichai is a chossid. the bochur answered. How did hamans daughter dump the garbage on hamman if she was above. the teretz is she saw hamans shtreimel. because haman and mordechai were both chasidim. but she thought it was vadai mordechai since haman was at the head. but she must of had a hava amina eleh mai they both wore a streimel.
some add haman and mordechai were both brothers whose father died. that is why they were fighting and why he did not ow down and assured from going to the tish.
