The Accidental Tsuris is the eleventh episode of the sixth season and 127th overall.
When Grace's rebellious, free-loading older sister Janet comes to town to launch her new jewelry enterprise/folding table subway stand, Grace decides to put her foot down casting her sibling away. However, when her tough love prompts Janet to go corporate by taking a 9-5 job and studio apartment, Grace can't seem to handle her new image. Meanwhile, Karen continues to spurn Lyle's proposals, only to have a change of heart after Lorraine stops by for an impromptu visit, to declare her disapproval over Karen's "relationship" with her father.
