I have seen lots of posts of mustache and lip clipart mixed in with Christmas themed props on Pinterest for people to use in taking Christmas card pictures.

I taped them to large popsicle sticks and viola, we have a fun tool to help kids visualize when to use he vs. she during our stories and drill practice.

"Who is laughing?" She is laughing.
I also like to use the props with puppets and books so it is done outside of drill with cards:
