I'm a big fan of MST3K. The OG seasons, not the reboots. As I watch what's going on currently I have two lines from S4E6, Attack of the Giant Leeches, stuck in my head.
Servo, as a general comment:
"These guys are aggressively incompetent."

Crow, speaking as one of ^ said guys:
"Keep in mind, I'm intensely stupid."

They were in my head 2016-20 too, but not so loud as now.
