Playing Silly Buggers

I have twin nephews who are now 25 years old. From an early age right up until now they are always playing silly buggers. Once when they were about 12 they came back into their coastal Mass. house with something wiggling under a towel. They had waylaid a seagull and let it loose in the house when they went to look at it. They had two Boston Terriers and a pug who all joined in the ruckus while the bird flapped frantically all around the living room until my sister opened the front door and it flew out.
