Can I become a professional spinner?
Would someone pay me to just
spin in circles for a little while?
Not for too long at a time
I might get dizzy and fall over.
Not really, that's typically how the "life debt" scenario works. Save a person's life, they pledge their servitude, their service is terrible (which is strange considering Spike is a good servant when it's with Twilight), the savior tries to get out of the deal, savior's life is saved. MLP isn't the first cartoon to have it, and it certainly won't be the last.
