Damon: I do believe in killing the messenger. Know why? It sends a message

It's Founder's Day. I'm here to eat cotton candy and steal your girl

I like being a living dead person

Damon about Elenas mother(Isobel) Leaving her:
"She left you. She sucks!" XD
Damon to Bonnie: "You weren't supposed to Witchy Migraine me!"
Stefan: "What happened tonight when you thought she was Elena?"
Damon: "To risk another frown line crouching on your already crowded forehead... We...Kissed." *smiles*
Elena: "And you thought It was me?"
Stefan: "what do you mean you kissed?"
Damon: "Well.. Yu knoew when.. Two lips pucker and they y'know *making kissing sounds*" XD
God he is so HILARIOUS! Love him!<33

Damon: "There`s no such thing as a bad idea. Only poorly executed awesome ones." [2.15]

Damon: "Some girls just can`t resist my good looks, my style, my charm and my unflinching ability to listen to Taylor Swift." [1.04]

Damon: ''If I see something I haven't seen before I'll throw a dollar at it'' [1.13]

Damon: "My new girlfriend. Andie Starr. Action News."
Alaric: It's not called Action News.
Damon: "I know. I like just saying it." [2.14]

He gets the best lines on the show! xD

Damon: “I just have to say it once. You just need to hear it. I love you, Elena. And it’s because I love you that I can’t be selfish with you. Why you can’t know this, I don’t deserve you, but my brother does. God, I wish that you didn’t have to forget this, but you do." [2.08]

Damon saying he´s sorry: "Sometimes I do things I don´t have to do"

Beggining of the episode 7, season 3: "Quiéreme" in Spanish, which means "Love me" in English. It´s the very first word Damon says:

Btw, Ian pronounces very well Spanish ♥
