Ya doing that is ****ing hilarious. The best thing to do though, is bind there swoop key to make them say "I'm such an idiot" and kill them self
admin_execclient
is the command
examples
To bind there fly key *default is f* to make them say something type this
admin_execclient namehere bind "f" "say Im an idiot"
That's how you bind things, you can also make them say things like this
admin_execclient namehere say "haha im an idiot"
you can also unbind all of there keys
But that I am keeping to myself
If anyone wants it I have created an Adminmod tutorial for doing funny things. Just pm me.
