-You might be an obsessed muppet fan if someone says aligators and you say "Read my lips, Al-i-ga-tors.".
-You might be an obsessed Muppet fan if you have your mom make you a kermit costume for Halloween one year and you end up wearing it for your entire childhood.
-You might be an obsessed muppet fan if your mom makes you a Benny Bunny costume
complete with bellhop bell (and maybe a suitcase)
-You might be an obsessed Muppet fan if you have dreams about a Sweetums theme park in northern Conneticut, but then go inside to find it's a Donkey Kong exhibit that shows real versions of the game characters.(i.e.- Chimps, Gorillas, aligators, etc.)
P.S.- These are all from my experiences.
