After spending a majority of the past 24 years watching Nickelodeon, I had a thought. Anyone who watched enough Nick noticed that characters cross over into other Nick shows. Whether it was a full blown crossover, like The Jimmy Timmy Power Hour, or just a quick cameo, Nick wasn't shy about sharing characters. So I was wondering, how many of these shows can be connected together? Since I'm an unproductive member of society, I decided to graph out how these shows connect with each other. This is what I came up with.

I'll break down how each show is connected but first I'll explain what the criteria was to establish a connection. In order to link two shows they must share a common character or significant object. That means actors playing two different roles in different shows do not count. Now that that's established, let's see how these 24 shows all connect.

All That and The Amanda Show

While Amanda Bynes played a character named in Amanda in both shows, it's unclear if that's the same character so I needed another link. The character Totally Kyle was in both All That and The Amanda Show, as was Amanda's stalker Penelope Taynt.

The Amanda Show and Drake & Josh

The final scene in the Drake & Josh series finale, "Really Big Shrimp" features a flashback to a scene from The Amanda Show where Drake and Josh are fighting over shrimp. A second connection is in the Dune Buggy episode, where The Amanda Show was playing in the background.

Drake & Josh and Unfabulous

In the Drake & Josh episode "Honor Council," Megan shows a video she made called "Doing Stuff to Josh While He Sleeps." In the video, she's with the main character in Unfabulous, Addie Singer.

Drake & Josh and Game Shakers

The manager of the movie theater in Drake & Josh, Helen Dubois, appears in the episode of Game Shakers "Tiny Pickles."

Drake & Josh and Victorious

Speaking of Helen, that character appeared as the replacement principal in the Victorious episode, "Helen Back Again."

Victorious and Big Time Rush

In the Victorious episode "Wi-Fi in the Sky" you can see a Big Time Rush poster behind Jade.

Big Time Rush and How to Rock

Big Time Rush and Marvin Marvin crossover as well, in the Marvin Marvin episode "Big Time Marvin."

Big Time Rush and Yo Gabba Gabba!

James and Logan from Big Time Rush met Yo Gabba Gabba! in yet another Big Time Rush crossover called, "Big Time Cameo."

Yo Gabba Gabba! and The Fresh Beat Band

The Fresh Beat Band had a crossover episode with Yo Gabba Gabba! called "Yo! Fresh Beats Go Gabba Gabba."

Yo Gabba Gabba! and True Jackson VP

Big Time Rush and SpongeBob Squarepants

In the episode "Big Time Beach Party", Big Time Rush hosts a beach party and one of the guests is SpongeBob's Patchy the Pirate.

SpongeBob Squarepants and Jimmy Neutron

In the Jimmy Neutron episodes "Operation Rescue Jet" and "The Evil Beneath" you can see parts of Bikini Bottom.

Jimmy Neutron and Planet Sheen

Pretty obvious, Planet Sheen is a spin-off from Jimmy Neutron.

Jimmy Neutron and The Fairly OddParents

Also self-explanatory, there were three Jimmy Neutron and Fairly OddParents crossovers.

The Fairly OddParents and Danny Phantom

In addition to the comic Crash Nebula being featured in both shows, in the Fairly OddParents episode "Poltergeeks" there is a Wanted warning for Danny Phantom.

The Fairly OddParents and Bunsen is A Beast

The episode "Beast of Friends" is a crossover between the two shows.

Victorious and iCarly

These two shows crossover in the special "iParty With Victorious."

iCarly and Zoey 101

The Zoey 101 character Stacey Dillsen has been in two episodes of iCarly, "iHire an Idiot" and "iStart a Fan War."

iCarly and Sam & Cat

Sam & Cat is a spin-off from iCarly and Victorious.

Sam & Cat and Henry Danger

Herb from Sam & Cat appears in the Henry Danger episode, "Secret Beef."

Henry Danger and The Thundermans

Henry Danger and The Thundermans crossover in the episode "Danger & Thunder."

The Thundermans and The Haunted Hathaways

The Thundermans and The Haunted Hathaways crossover in the episode "Haunted Thundermans."

As time goes on this list will just keep growing, especially if Dan Schneider keeps making shows.
