Another pun:
I used to hate crayons but I’m drawn to them now.

Explanation: Crayons are used for drawing.  “To be drawn to something” means that something is enticing, attractive, makes you want to approach it or get to know it.  I love water so when I see it, I am drawn to water.  I am also drawn to chocolate and coffee.  My students are drawn to the game Pokémon Go on their phones.  This pun is funny because of the use of the word “drawn.”
