My sister senmt me this one; there's nothing essentially Jewish about the joke, except, perhaps, something about attitude(?).
Two old jewish guys, Saul and Hiram, are talking: S: Whassat? H: What? This? This is my jar of bees. S What for? H: What for? For my hobby. I collect bees. It's my hobby. S: Why don't you punch some holes in the lid? H: Whaffor? S: They could breathe, they'd live longer. H (shrugging): It's only a hobby. hugs and matso balls, Walt
