Example: When he read SpongeBob’s diary’s.
UTST i think
Club SpongeBob.
When he is being a general grump and/or mean to spongebob in the beginning of the episode when SB did nothing to him
The Whole Tooth: He made fun of Patrick.
"Naughty Nautical Neighbors" is usually the first that comes to mind, but "Mind the Gap" and "I Heart Dancing" are other examples of time he did things that actually warranted his punishments in their respective episodes.
What do you think?
