Same for me mate, in terms of who I find funniest anyway. Pure anarchy is one of my favourite forms of comedy. Like Vivian in the Young Ones casually kicking the bannister to bits when he walks down the stairs. That kind of stuff creases me.
However my favourite Muppet overall is Gonzo. Love him. Heās part of my two favourite Muppet combinations too, him and Rizzo in the Muppet Christmas Carol, and when him Rizzo and Pepe share an apartment in ABCās The Muppets.
I am willing to write more about why I like the Muppets if you want me to.
