Barney claims he was jealous of Clint, revealing he had once kissed Ted's mother while dropping her off at the airport after their brunch in 2006, though the rest of the group doubts his story.
Dejected, Ted wonders if he will ever have the life he dreams of; Lily cheers him up by telling him to bash at the house with a sledgehammer, and the whole group has fun smashing a wall with it.
She said the episode exposed a different angle on Ted's love story by showing where his future family would live.
She noted the execution of Marshall's Drunk or Kid game and Barney's exaggerated recollections were a bit off.
[1] Cindy McLennan of Television Without Pity also gave the episode a B+ score, citing the implausibility of having a real-estate inspector study the house when Ted's architecture skills can determine the flaws as well.
