Donna and Jackie,the two girls of the current sitcom"That 70s Show",seem to be quite simular to Blair and Jo.Jackie being a somewhat stuck up perfectionist like Blair,while Donna appears to have a tough tomboy personality like Jo.Not to mention,the way Donna and Jackie famously cut eachother up,bores another resemblance to Blair and Jo.I wonder if this is just a coincidence , or maybe the formula of the Blair & Jo relationship was borrowed for Donna & Jackie's relationship.
