Walt's best and worst lies

As a man living a double life, Walt is frequently put into a position of having to come up with some wild whoppers to account for his actions. Once Skyler finds out the truth of the methmaking by season 3, she's occasionally forced to spin some yarns of her own. Some of these subterfuges work better than others. Here are, off the top of my head and in no certain order, the best and worst lies Walt tells and I would be curious if others can think of some more:

THE BEST:
1. Bugging Hank's office part 1--Walt in pure thespian mode, making himself look weak and cowardly, bawling buckets of fake tears. It works as planned: Hank is disoriented (not used to a man expressing himself that way) but one senses he's still sympathetic to a brother-in-law confessing his marriage is falling apart.
2. "The gambling story"--credit for this one should technically be given to Skyler, who whips up an.elaborate scenario to account for Walt's sudden financial windfall.
3. "Fugue state"--an elaborate and complicated lie to account for Walt's disappearance, lest Hank suspect a connection to Tuco. When he realizes he might be committed, he tells a sort of half-truth to a psychiatrist that gets him a speedy passage out of the hospital.
4. "The Confession Tape"--Walt makes up a whale of a tale casting Hank as the mastermind behind Walt's meth operations. Hank is smart enough to recognize it as a threat, momentarily derailing Hank's investigation and forcing him into silence with his colleagues at the DEA.
5. "Tow the line, or you will end up just like Hank"--Walt enacting Heisenberg on steroids, deliberately performing for the cops who are listening in. Even Saul praises this one, recognizing as something that will play great for a grand jury, insuring Skyler's exoneration.

THE WORST:
1. "Fuel pump malfunction"--Walt has to explain why the living room carpet has that gasoline smell. Skyler doesn't fall for it in the least.
2. Bugging/debugging Hank's office part 2 -- Hank may have been sympathetic the first time, but Walt's histrionic tears are beginning to grow tiresome to him by now. You sense he thinks he's dealing with a total wimp. Walt goes through the motions, but he doesn't invest the spirit he did the first time. This scene plays as much more comical than the first.
3. "He sells me marijuana"--Walt's early lie to Skyler on how he knows Jesse. It's an OK lie and gets the job done: Skyler is momentarily thrown off his trail, but it doesn't achieve the Shakespearean heights of the lies he tells in later seasons.
4. "Second cell phone"--Walt comes up with a too-detailed fib on why Skyler heard an unexpected ringtone
5. "I"m going to my mother's for a few days"--a lie it would be too easy for Skyler to figure out, which she eventually does. Walt still in amateur mode.
