Times Table Takedown

I have a third grade student passenger who sits about half way to the back of the bus. Two days ago, he requested to sit right behind me after the students that regularly sit there, departed. He's done this in the past, usually because he has something on his mind or he wants to ask me a question. He's a good kid and I don't mind a question or two or helping him by just listening. The tables got turned on me the other day... or should I say... the times tables got turned.

TWO DAYS AGO
(3rd Grader) "Mr. Stuckey, what's 4 x 7?"
(Me) "28."
(3rd Grader) "What's 7 x 8?"
(Me) "56."
(3rd Grader) "What's 8 x 9?"
(Me) "72."
(3rd Grader) "Okay thanks."

YESTERDAY
(3rd Grader) "Hey Bus Driver, what's 4 x 9?"
(Me) "36."
(3rd Grader) "And what's 7 x 7?"
(Me) "That would be 49."
(3rd) "There... my homework's all done."
(Me) "Wait... did you just dupe me into doing your homework?
(3rd Grader) "What's dupe mean?"
(Me) "Tricked... did you trick me into doing your math homework?"
(3rd Grader) "Well technically no because I filled out the paper."
(Me) "But I gave you the answers. The point of homework is for you to do the lesson so you can learn how to find the answer yourself........ By the way... how did I do yesterday?"
(3rd Grader) "We got a 100%."
(Me) "WE got 100%?"
(3rd Grader) "Technically... yes."
