I'll start with:
^ (stick mummy who has jumped so high her top half can't be seen above the door sill)
X a star jump with splits
O a weebly dance for those who are pregnant but want to join in (tho' I am not pregnant, it's good to have solidarity with the MNers who are)
K a one-sided Saturday Night Fever pose
Now I'm all sweaty, and I've danced like a fool without even had a drink. Will someone come and join me?
