You can watch a preview of this episode at Australia's Turbonick. Although I don't live in Australia, their Turbonick works fine on my computer.

EDIT: For those you cannot see it, here is how the preview goes.

Mr. Krabs has a yellow blindfold on his head. He is not sure if Plankton will catch him if he falls. He falls and Plankton can barely catch him. Now, Mr. Krabs trusts Plankton and to prove it, he gives away the secret formula. At first Plankton doesn't want it, but changes his mind. After Plankton gets the formula, he cheers in an evil way because he finally got the formula. He runs and reads the formula, however the paper says, "Gotcha! Love Krabs." Mr. Krabs comes up to Plankton and tells him that he'll never give away the formula and he fooled him. Mr. Krabs leaves and Plankton shrieks.
