You know that Sponge-Bob episode.....?

OK there is an episode of Sponge-Bob my brother was just watching and in it, there is a garbage can and Sponge-Bob reads what is on it and on it it says, "Squid-ward stinks" and stuff but then it says, "Krabs is a _______" and I have an idea of what the blank is but I am not positive.....? Because I tried putting differant words in when you heard the dolphin noise (beep when they said the word) and I am not sure which word it is...? Help! I am going to be paraniod for days if I don't know!!
