Cool, I didn't notice Mac and Goo escaping from the Mandy 2X4 technology-bot. I must watch it closer next time. I thought it was funny when Fred Fredburger says something like "I like monkeys who go to school. I also like monkeys who go to camp! And I like imaginary friends! I like imaginary monkeys!" ...Yeah, typical Fred, but it was still funny.
I never watched Samurai Jack so I wasn't familiar with the reference at the end, but I liked it. Mac looked cool. And I bet Bloo loved wearing those teeth for that shot.
