SpongeBob: "Did you notice the seaweed on the victim's shoes?"
"Does this seaweed remind you of someone?"
"Victor was probably poisoned before he got here. It's the only explanation for the stop in his breathing."
"We're going to the Krusty Krab to check it out"
"I bet Mr. Krabs has something to do with it."
"Hmm, Mr. Krabs' claws are suspiciously clean. Look at how they gleam!"
"He could use them to kill a person"
"And look at all these Krabby Patties! They're perfectly cooked, but why is Mr. Krabs so nervous?"
"Excuse me, Mr. Krabs! Did you have anything to do with Victor's death?"
"Mr. Krabs, we found seaweed on the victim's shoes. It's the exact same kind you serve with your Krabby Patties. Care to explain?"
"Mr. Krabs, if you don't tell us the truth now, we'll have to arrest you for suspicion in Victor's death!"
"Fine, but if I find out you're lying, you'll be behind bars faster than you can say 'Krabby Patty'!"
I say I know who killed him
"Well, Mr. Krabs, it looks like you're off the hook. Who did you say killed him?"
"Plankton?! But he's so small! How could he possibly have killed someone?"
"he has 1000 year old kryptonian-tech that he stole from me when I was a kid"
"Mr. Krabs, is that true?"
