Teasing and humor is at its funniest when it is observational. Canned lines are corny and only are effective as such. Minus the classics.
Be aware of your surroundings, be aware of her, and find the humor in the daily things that happened in life. I was at work on the 3rd story and glanced out the window, I seen smoke and a guy barbequeing. He must've climbed out the window to setup his grill, wtf? Lol
