A Florida family captured video of a pair of unusual trespassers -- black bear cubs -- out to have a good time on the family's backyard trampoline. Jennifer Pacheco of Naples and her daughter, Paige, said they were on their back porch in Naples Thursday when their dog, Sheldon, alerted them that something was unusual. "He was barking and then we looked back there and there was the two bears." Paige Pacheco told WFTX-TV. Jennifer Pacheco said she immediately knew she had to "grab my phone and start videoing it because it was a sight to be seen." The Pachecos said the bears bounced for more than half an hour before leaving their yard.
