Really simple, and lots of fun. The aim of the game is to make the other people smile!
The group sit in a circle, one person is “it”.
The “it” person goes around the group in turn, saying:
Honey, if you love me, just give me a smile.
To which his target responds:
Honey, you know I love you, but I just can’t smile.
If the target manages to say this without smiling, the person who is “it” moves on. If the target does smile, they become “it”, and the person who was “it” sits down in their place.
The person who is “it” is allowed to do almost anything to try and make the person smile (funny faces, silly actions, etc), but it is good to establish rules for what physical contact, if any, is allowed. The target also has to maintain eye-contact while saying their line.
