Historical (personal) examples of teachingbased research
I had a feeling there should be a Conway example, but couldn't remember one off the top of my head

Why aren't representations of monoids studied so much?
Assuming your latest comment is not an April Fool's joke, I look forward to reading this (although I admit I don't think about semigroups as much as I used to)

Show that among any 6 nonnegative integers one can find 2 integers so that their difference is divisible by 5
@JoeSchmoe No problem  it's an easy, honest mistake to make. Good luck getting help with your question, although as always I would recommend getting some help from a fellow student or a course instructor if possible.

@AdamP.Goucher It should be noted that the whole business of "MSE is the place to go to get help with homework" is a sore point with some people; the behaviour of some antiantihomework people is the reason I deleted myself from MSE and will probably never return...

Why could Mertens not prove the prime number theorem?
Well, I'm sure that grammar correction was well worth resurrecting this question for.

Proof that no differentiable spacefilling curve exists
To Joseph O'Rourke: could you please clarify whether you had $C^1$ in mind during your question?

comment 
Proof that no differentiable spacefilling curve exists
@LennartMeier Yes, I know that Sard would apply in this case for $C^1$. My point (although perhaps not one that the OP had in mind) is that $C^1$ is strictly stronger than being everywhere differentiable, and for these kinds of functions I have no good intuition whether that makes a difference to the original question

@QiaochuYuan isn't Sard's theorem about $C^k$ maps? And the question asks for differentiable, not $C^1$...

Lovasz's Path removal conjecture
Currently the question has votes to close as "unclear what is being asked". I think it is reasonably clear what is being asked: the OP wants to know which theorem in Tutte's paper states and proves the result mentioned in her first paragraph
