Tell her that Tamaki and her would make a cute couple
Play thunder sounds near her on your phone
Constantly sing to her "Tamaki and Haruhi sitting in a tree k i s s i n g"
Poke her face until she tells you to stop, then poke her face again.
If a girl reserves Haruhi, tag along and tell that you are a Club Member in training. Then, when things heat up a little, kiss her right on the lips.
Hold your finger an inch away from her face ands say "I'm not touching you"
Bring her to Tamaki and push their faces together saying "now kiss"
----------------------------------------------sorry it's short but Haruhi isn't easy to annoy! Lol
