The voice of everyone's favorite grumpy cartoon squid was arrested Friday night for DUI.

Rodger Bumpass, the voice actor who plays Squidward Tentacles on Nickelodeon's SpongeBob SquarePants, was arrested after failing a field sobriety test on Friday.

TMZ's law enforcement sources say police noticed a man leaning against a blue PT Cruiser parked in the middle of a road just before 11 p.m. When they walked up to the man (Bumpass), they say he walked away - nearly falling, as he was so unsteady.

Bumpass' blood alcohol level was over twice the legal limit.
