What is something cool crazy and clever to put in a birthday card?

Okay, here's the deal. It's my dance teacher's 17th birthday today, but it was a busy 日 and I couldn't get her anything (I was thinking a card and something hello kitty--- she likes hello kitty as do I, but I digress) So I have to make a homemade card with a piece of paper I *poorly* ripped out of my science journal. I NEED HELP! What are some cute this to draw and say for Ms.Nia? please hurry, I have to get dressed and ready for dance によって about 5:00 Eastern Standard Time...
