1. He is always hurting Joey.
    Remember the one where Joey buys him the bracelet? I certainly do.
  2. He kissed joey's Girlfriend.
    Need I say more?
  3. He goes against Joey's wishes and tries to get him to accept money, even though he doesn't want it.
    Like, come on! Respect your friend, man!
  4. He's homophobic.
    Okay, I get his dad left his mom for another man, but it's still not okay.
  5. He's a pervert.
    Okay, maybe I'm biased, but I feel like there is a difference between when Joey is being a creeper and when Chandler is. But if you pay attention, Chandler says a lot more creepy things, and they usually out-creep anything Joey says.
  6. He was a giant bag of d*cks to Janice.
    So her voice can be a little annoying, but she always deserved better.
  7. He constantly lets his insecurities and baggage get in the way of his relationships.
    How Monica put up with it, I'll never know. (But I'm glad she did. They make a better couple than Ross and Rachel.)
  8. He kissed Joey's sister and then forgot who she was.
    STOP KISSING PEOPLE JOEY CARES ABOUT. And no, being drunk is not a valid excuse.
  9. He watches porn, even though he is married.
    Maybe I'm old fashioned, but I don't really think porn has a place in a marriage? Especially when you lie about it and hide it from your significant other. And then it all gets swept under the rug because people are just happy he isn't sexually aroused by sharks?
  10. He is irresponsible and immature.
    I feel like I don't need any examples, but I'll give one anyway: when he agrees to move to Buffalo because he can't tell the truth to his boss. Lying is a consistent theme with Chandler, actually.
  11. He always makes humorless jokes in inappropriate situations.
    I get that it's a defense mechanism, but he needs to work through that. It's not a healthy way to deal with stress/grief/awkwardness.
  12. He is weak and selfish.
    He stopped a man's promotion because he was to weak to tell him he had been of calling him the wrong name. For years.
  13. His hairstyle in collage.
    Never forget.
