Plot summary
Tammy needs a truck for her burgeoning contractor business and brings Bonnie with her to buy one. But after Tammy buys an expensive truck outright with cash on hand, Bonnie starts to feel like a failure and is both jealous of Tammy's success and upset by her jealousy. Eventually, Bonnie admits how she feels to Tammy and later gets Tammy a big rate increase on a kitchen job, leading the two of them to agree to go into business together. Elsewhere, Wendy's enthusiasm for a dance class despite her bad dancing helps Jill realize that she has missed out on a lot of good things because of her perfectionism; Jill then pays Andy a visit where she gives him a (poorly made) piece of pottery and tells him that their time together wasn't perfect – but it was wonderful and she has no regrets about any of it.
Title meaning: Jill's post-dance workout rush feeling and what Marjorie feels after Tammy turns on the seat warmers in her new truck. Trivia note: This was the 1st episode the show produced after being informed by CBS that Season 8 would be the show's last one.
