In the last ever brand new episode of "Victorious", titled "Victori-Yes", teacher Erwin Sikowitz (portrayed by Nickelodeon Star Eric Lange) challenges the students to say yes to everything for one week.

The Victorious Series Finale is This Weekend
It’s hard for us to say this, but the ‘Victorious’ series finale is almost upon us. This Saturday, February 2 is when fans will be able to see the very last episode of the Nickelodeon show. Yeah, we’ll be seeing Cat Valentine (Ariana Grande) on Nick’s upcoming ‘Sam & Cat,’ but we’re still going to miss Tori, Andre, and the rest of the crew. Series creator Dan Schneider tweeted about the finale “NEXT SATURDAY NIGHT (Feb 2nd) will be the LAST EPISODE of @Victorious. I hope you’ll watch. Make some popcorn. Watch with some friends.” This is going to be a big send off. We can’t wait to see the finale, but we’re going to miss ‘Victorious’ once it’s gone.
