I just thought of another one that I don't like that everyone else does.
Coffee 
(I think I might have just isolated myself from most of you coffee lovers - you coffee lovers will still like me, right? 

 )
PC - I'm the same.  I like it hot HOT and cold COLD, rarely nothing in between.  I can even eat/drink exceptionally HOT food while others have to blow on it a couple of times.  I'd like to think I got it from my Dad.
