In "Opposite Day" the backwards dialog is, "Hey Patrick." "I give up." "To get to the opposite side." "Hahahahahahaha."
In "Nature Pants", when SpongeBob leaves to start his new "nature" life, Sandy says "I'll give him a week." Squidward replies, "I'll give him eleven minutes." This is referencing the fact that each episode is approximately eleven and a half minutes, meaning Squidward won the bet.
In 2018, two scenes of Nature Pants became two internet memes, one with SpongeBob catching his breath and Patrick's expression is named Evil Patrick.
