Ten things to do on FOnline.....
1. Get Blacklisted by gangs big and small and have them hunt you down!
2. Random Fail murders in NCR!
3. Thief Fails!
4. Deathclaw hunting with a switch! (like Doc Mitchell from Fallout New Vegas always says.....)
5. Punching out Enclave/BoS!
6. Tent/Base Raping!
7. Get people to hate you!
8. Random acts of trolling/other!
9. Go on a quest to find a cookie!
10. Eat the Cookie!
(Most of these are not recommended to do and not tested by me and will get people to hate you/hunt you/troll you/kill you/etc and will probably get you killed.....)
Hope you have fun!
Edit:Everyone add more things to do in replies!
