Peter is gonna learn for school

"Well, dad... I am gonna learn for school since I got an exam coming up at the end of the week.".
"Oh... And what am I gonna do now?" Walter asked.
See, Walter was currently unemployed, leaving his wife Rebecca as the only cash bringer of the family right now.
"Well Dad, maybe you could use the device to earn us some money, no? Oh, and could you lend me the device?" Peter laughed diabolically.
"Son, what are you getting at?" Walter frowned.
