I really like food and I really like music. I play the piano. Eating and making/or listening to music are easily my favorite activities. I also really like traveling, especially when I can eat really delicious foreign food and listen to really good foreign music.
Also, I will always and forever find "that's what she said" jokes hilarious, so if you find that immature you should probably keep it moving AND reassess your sense of humor. Other things that make me laugh (because laughing is important): most inappropriate jokes, rowdy games of telephone pictionary, the Office, awkward coworkers who remind me of Office characters, Liz Lemon, the "shit white girls say to black girls video," sarcasm, Family Guy, the list goes on.
