First, kidnap the particular fan.

Then use a knife to cut the fan, the more the better.

After that, sprinkle salt on the wounds. (It'll be better if you pour the whole packet of salt on the whole body.)

When the fan is dying of pain, pour vinegar on the wounds. (Another me: are you cooking? =,=||)

When he/she has fainted, throw him/her into a pond/drain/lake etc. (I actually wrote drain at first...)

Disclaimer: All of the above is just for your entertainment, I'm not that cruel... (Are you sure?? =,=||)
