I once saw a photo of an RSVP card worded as such:
[ ] Accepts with pleasure
[ ] Accepts with regret
[ ] Declines with pleasure
[ ] Declines with regret
I found it funny, but I was curious about how others would react.
I also remember seeing a card with a photo next to "accept" with the B&G smiling and a photo next to "decline" with them flipping the camera off. Seems like something that was fun in concept but awkward in practice... My aunt doesn't need to see anyone flipping her the bird!
