In 'Church of Metropolis', Superman smashes the monitor(s) in the secret lair after tracking the bug they tried to plant on Clark back to it. Yeah, they're bad guys, but it's still destruction of private property. He should also get a slap on the wrist for the punny, "Now stop bugging people!" while smashing it. :p

ETA: He also puts his fist through the television in the Planet's newsroom as Superman in 'Don't Tug on Superman's Cape' after he thinks Bad Brain zapped Lois into a pile of ashes.

Lois: You know, I have a funny feeling that you didn't tell me your biggest secret.

Clark: Well, just to put your little mind at ease, Lois, you're right.
