Unexpected supporters

One of the things that has been recently calling me attention while walking around is how characters or people that don't have any direct connection to the content where they are being used appear in order to serve other purposes or simply to call our attention.
If it is not a big surprise that Che Guevara appears here and there, some others are pretty surprising and even funny, like the usage of Statler and Waldorf of the Muppets, just like I've presented in this post.
Here are some more examples:

Peter Pan for an anarchist movement 

Skeletor from the 80's children's animation series He-Man 

Charles Schulz's Charlie Brown also with anarchist motivations

 

Grumpy Cat 

 

The Simpsons supporting St. Pauli

Jack Nicholson playing McMurphy on One flew over the Cuckoo's Nest

 

The Dalton brothers from Lucky Luke
