 The bar s furnace is on the fritz, so Rebecca calls the furnace company to fix the problem. While she s got them on the phone, she has to crawl in through the vent in the wall - usually covered by a grate - to get some information. Carla uses this opportunity to put the grate back into place and leave Rebecca locked in the vent in the wall. Later, Paul tells Rebecca that she can get back at Carla by throwing her purse in the vent, so that Carla will have to climb in and retrieve it. Rebecca does so, but it happens to be her own purse, so she has to climb back in and retrieve it. Carla paid Paul to do it, and Carla once again locks Rebecca in the vent in the wall. With other official bar business, Sam offers the bar employees a medical plan. Each employee must take a blood test. Carla refuses as she s scared of needles. Frasier uses his psychiatric skills to get Carla under the needle. Meanwhile, Woody and Kelly are having their official engagement party, at which Woody will meet for the first time Grandmother Gaines, who has a reputation for being tough as nails. Equally as troublesome for Woody is that he cannot afford Kelly s engagement ring and is forced to work a second job at a graveyard to pay for it. The second job takes its toll on Woody as he s not getting any sleep and is further exhausted by selling his blood. This day is particularly bad as he further took his employee blood test at the bar, and had a tough night at the graveyard with the difficult burial of Mrs. Jane Vanderhoeven, whose casket kept on popping open. What s worse is that he forgot that the Gaines  moved the day of the party up one day to today. Woody s in no real shape to go, but he has no choice. At the party, Woody is still a little woozy, but he has to meet Grandmother Gaines. Woody is totally freaked when he meets Grandmother Gaines: he swears that she is the supposedly deceased Mrs. Jane Vanderhoeven, the woman he buried last night. Grandmother Gaines wants to have a private talk with Woody, for which he is obviously frightened. At the end of their short talk, Grandmother Gaines states that Woody tried to bury her the previous evening. Woody s darkest nightmare has come true. In reality, Grandmother Gaines, in an effort to catch Woody in his true light but to also play a joke on him, pretended to be the deceased Mrs. Jane Vanderhoeven the night before at the graveyard. Woody is mad and really wants to kill Grandmother, but Grandmother really likes Woody, likes his grit and honesty, and gives her blessing to Kelly and Woody on a happy marriage.
