It explains lutefisk.

Quote from Garrison Keillor's book Lake Wobegon Days: Every Advent we entered the purgatory of lutefisk, a repulsive gelatinous fishlike dish that tasted of soap and gave off an odor that would gag a goat. We did this in honor of Norwegian ancestors, much as if survivors of a famine might celebrate their deliverance by feasting on elm bark. I always felt the cold creeps as Advent approached, knowing that this dread delicacy would be put before me and I'd be told, "Just have a little." Eating a little was like vomiting a little, just as bad as a lot.

Quote from Garrison Keillor's book Pontoon: Lutefisk is cod that has been dried in a lye solution. It looks like the desiccated cadavers of squirrels run over by trucks, but after it is soaked and reconstituted and the lye is washed out and it's cooked, it looks more fish-related, though with lutefisk, the window of success is small. It can be tasty, but the statistics aren't on your side. It is the hereditary delicacy of Swedes and Norwegians who serve it around the holidays, in memory of their ancestors, who ate it because they were poor. Most lutefisk is not edible by normal people. It is reminiscent of the afterbirth of a dog or the world's largest chunk of phlegm.

Interview with Jeffrey Steingarten, author of The Man Who Ate Everything (translated quote from a 1999 article in Norwegian newspaper Dagbladet): Lutefisk is not food, it is a weapon of mass destruction. It is currently the only exception for the man who ate everything. Otherwise, I am fairly liberal, I gladly eat worms and insects, but I draw the line on lutefisk.

• the above is from Wikipedia entry on lutefisk. Believe it or not.

I sometimes find that telling my Inner Lazy that it can decide—after I've done the first one—between whether to continue a series of tasks or to stop and be Lazy gets me to do the whole series of tasks. Despite having noticed explicitly that in practice this 'decision delay strategy' leads to the whole series getting done, it still works, and rather seems like tricking my Inner Lazy to transition into/hand the reins over to into my Inner Agent.

Accountability check!

Did you do it? How'd it go?

Betcha it'd work.

Oh, bother. I wish I'd seen this earlier.

create an Ugh Field and undermine all future self-discipline attempts

That's one way it could play out. It feels like this thinking also allows for it to work, because one might feel good about what got done by means of the trick, which would positively reinforce being tricked. I think the matter isn't clear cut.

I don't think you are correct.

The miser knows each time he will not get the reward, and that he will save on food and drink. That is the real reward, and the rest is a kabuki play he puts on for less-important impulses, to temporarily allow him to restrain them in service of his larger goal. The end pleasure of savings will provide strong positive reinforcement.

This could probably be empirically tested, to see if it is true and would work as a technique. I can imagine a test where someone is promised candy, and anticipates it while acting to fulfill a task, and then is rewarded instead with a dollar. Do they learn disappointment, or does the greater pleasure of money outweigh the candy? This is predicated on the idea that they would prefer the money, of course - you would need to tinker with amounts before the experiment might give useful results.
