[It's Always Sunny in Philidelphia] We know what happens on Mac and Dee Day, but what happens on Charlie Day (pun not intended), Frank Day and Dennis Day?

Pretty much the same as Mac Day except they would do things they enjoy.  

 Frank- probably revolving around drugs and whores. He probably makes the gang treat him with respect.     

Dennis- lots of compliments and all around worship. He probably also tries to get them to do classier things.    

Charlie- hunt for ghouls and goblins(they mention it in Mac Day)
