Bucket list for wearing horse head mask

I and my friends ordered horse head masks (if you haven't seen them look it up) and we've started a bucket list for wearing them that has to be completed within three

months. if not, we have to face some sort of punishment. that's chosen by the other two and yeah

This is all we have so far;
1. Go and eat at Sonic
2. Go to the gas station
3. Dance with random people downtown
4. Take a photoshoot
5. Run around at the beach
6. Play soccer
7. Dance like Michael Jackson in public
8. Convince somebody not to buy what they're picking out at a grocery store
9. Neigh at 10 people as they pass
10. Chase after somebody
11. Play Hide and Go Seek with other signers while at Wal-mart
12. Play Nerf Gun War in public with other signers
13. Walk your dog

That's all we have. we've been trying to think of more ideas.

I find that some famous stars like to wear horse head mask.why they do that and even public photos which they wear horse head mask.Does they do this in order to get the attention of others ?What do you think of this thing?
