King of the Ant Hill is a very telling episode about Hank and his relationship with his lawn. He gives a short monologue early on about his feelings for the grass as opposed to the feeling he should show for those most important in his life. Best quote: "without my lawn, I am Bill". Luanne gets a short, retarted scene in this one where she shows her truly unimpressive tact and common sense outdoors. **SPOILERS**
Hank gets razzed by Mr. Kahn about the condition of his cherished lawn and resorts to dumping Dale as his exclusive lawn care professional exterminator. He goes out and purchases the most expensive grass implants at the lawna and garden store(Raleigh Saint Augustine)and Dale wreaks a horrible, illogical revenge on the beautiful lawn. His feelings are so hurt by being refused the privilege of helping to protect Hank's lawn, he actually drops a load of fire-ants onto it on purpose. In the subplot, Bobby gets a strange mental effect from huffing the essense of the Queeen fire-ant in his room and goes through the episode in a kind of trance. He is under the control of the fire-ants!
Tune in for a ton of laughs.
