Liz hopes a Valentine's Day root canal will make her feel better about being alone. Jack goes after an attractive CNBC host. Jenna is crushed when a stalker stops stalking her.

Barney and his father, Jerry Whitiker, meet for the first time as father and son. The rest of the gang are struggling with certain issues - each has a "gap in knowledge".

One of Lois' relatives passes away, leaving Lois and the rest of the family her posh summer mansion in a will. However, when Peter becomes convinced that he is rich and ultimately bids $100 million at a charity auction, he attempts to convince the landowners his house is valuable enough to trade instead. After several futile attempts to "prove" that Cherrywood Manor has enough historical value to cover the bid, Peter makes up with Lois and uncovers a set of hidden photographs which show several prominent American figures (including Abraham Lincoln, Robert E. Lee, and Ulysses S. Grant) at Cherrywood Manor, which was a whorehouse at the time. This discovery allows Peter to buy back his home after selling the pictures to the tabloids. Afterwards, Peter decides that he does not care what Lois' relatives think of him, calling them "a bunch of pimps and whores".
