Reasons my kids (Alexey and Sergei) do not do their homework.

Physics:

1. I accidentally mixed my homework with my anti-homework, and it exploded.
2. The gravitational constant changed sign, and my homework flew away.
3. I tried to build a black hole in my bedroom when my homework suddenly disappeared.
4. According to Newton's third law, for every action, there is an equal and opposite reaction. I was afraid of what my homework could do to me if I worked on it too hard.
5. My biology homework ate my physics homework!
6. My Physics homework disintegrated into atoms and fell through my floor to say hello to my neighbors.
7. I can't go against conservation of energy and the minimal action principle.

Mathematics:

1. I had a constant amount of homework. I tried to derive its purpose, but I got nothing.
2. I assumed that all the homework you assigned me was Abelian, so I thought that I could pass it in and then do it.
3. I could only get arbitrarily close to my textbook, but I could never reach it.
4. I am sure that I put it inside my Klein Bottle last night, but this morning I could not find it.
5. I locked it in my trunk, but a four-dimensional dog got in and ate it.
6. My little sister cut it into a finite number of pieces, and when I put it back together, I got a proof of the Banach-Tarski Paradox.
7. I did part of it; the part I have left to do, is 0.999999999...
8. My homework is a constructive demonstration of Godel's Incompleteness Theorem. That is, it is possible to assign a homework that cannot be completed.
9. I wanted to, but I couldn't find its Godel Number.
10. I completed my homework, but then I beheld it and saw that it lacked character, personality - there was no "me" in it, so I multiplied it by i, and it became imaginary!

Programming:

1. I accidentally overwrote my last reference to it, and it got garbage-collected.
2. I accidentally divided by zero and my computer burst into flames.
3. I wrote "pink elephants" as an answer to one of the homework questions, and it threw a null pointer exception.
4. You didn't initialize the essay length, so I defaulted it to zero.
5. My homework made itself read-only, and I didn't have root access.
6. I accidentally wrote "rm -rf /*" on my homework, and it disappeared!
7. My mother redefined my doTheHomework() method with { doTheDishes(); }.
8. I outsourced it to China, but they were sleeping.
9. My homework had a pointer to Civilization III, so I did that.
10. I accidentally invoked my do() method on the laundry instead of my homework.

History:

1. My homework was exiled to Elba for its crimes, and so I couldn't bring it to school.

Miscellaneous:

1. I didn't have enough Vespene gas.
2. My grade is irrelevant, my homework is futile.
3. Those nasty hobbitsess stoless it from us, precioussss...
4. I suffered a Memory Lapse, and it ended up on top of my library.
5. I started my homework, but it became more powerful than I could ever imagine.
6. I accidentally pressed the self-destruct button, but the cancellation button was out of order.
7. My homework was consumed by the power of the One Ring, and it no longer submitted to my will.
8. There is no homework.
9. I was thinking of the top ten reasons as to why I didn't do my homework.
