Shows like Austin & Ally, Jessie, and Shake It Up are so awesome that they can completely stand alone. But what happens when they join forces with other shows? Crossover episodes are probably the coolest thing to ever happen on television. Remember Wizards on Deck with Hannah Montana? Or the iCarly/Victorious mashup? It's always amazing when your fave TV characters cross the barriers of their own shows and make friends with characters from other series!
Later this month, we have a brand new crossover episode to look forward to: Teddy and PJ from Good Luck Charlie are heading to NYC where they'll meet Jessie! While we wait for the premiere of Good Luck Jessie: NYC Christmas on November 29, M thought it'd be pretty cool to take a look back at some of our favorite crossover episodes of all time.
