Music makes me very, very happy. Coheed & Cambria, Brand New, Alexisonfire, The Blackout, Skrillex, Gallows (with Frank, not without), Anti-Flag, The Rocket Summer, City & Colour, Parkway Drive, Atreyu, Less Than Jake, A Skylit Drive, TRC, Taking Back Sunday, Rise Against and Reel Big Fish all make me smile.
Filmwise, I love Garden State, Edward Scissorhands, Drive, Anna Karenina, Where The Wild Things Are, Whip It, Moulin Rouge and Fight Club. And generally anything involving Ed Norton. I dislike Submarine a lot.
The only tv show I really love more than life is Game of Thrones. But I am quite partial to old episodes of The O.C.
Cider at festivals
Really, really good books.
Hot toddies (regardless of the season)
Hot water bottles (the same applies)
