Bart went back into time. Again. But this time, for a different reason, why? He wanted to see his mentor when they were a teen and possibly mess with them.

He successfully did travel back in time and hid somewhere to avoid his mentor's glance as he watched them do patrol by themselves as he snickers. Anyway, he had a plan. How could he talk to them? Besides, they looked very awesome here, and he didn't wanna mess up their little moment here.
