I love Eeyore...definitely fits my personality. My screen name on most sites is grumpjes24 if that is any clue. LOL
My boyfriend on the other hand LOVES Tigger. So much, that when we went to Disneyland last year, we stood in line without kids (My dd was visiting grandma) to get his pic with Tigger. (But in all fairness, I got my pic with Eeyore, since we were in line and all )
No contest here, being a Tigger I have to vote for Tigger! I love Eeyore too. (I don't quite see the appeal of Rabbit honestly, but maybe it's because I'm a Tigger that Rabbit wouldn't like too much! )
