Can you put sugar on your finger and let me lick it off?

"Can you put sugar on your finger and let me lick it off?" This is what Luke asked our friend Mindy at a cookout this weekend! He also asked another friend if she knew how dogs and cats kissed. He then proceeded to show her that they kiss by wiggling their tongues at each other. We have no idea where he got any of these ideas, but we were cracking up the entire night!
