Doneky Rentals For My Parents Anniversary

Hey everyone my relative requested that i find a place that rents donkeys, don`t ask...its for my parents 25th anniversary and he is notorious for playing pranks at parties. The anniversary will be on saturday, march 12th 2005 in lynn massachusetts, which is close to revere. If someone can please help me find a place in massachusetts where i can rent 2 donkeys for about half an hour i would greatly appreciate. Thanks so much
