Cl0wned
Achievement: Honk the noses of 10 clowns.
The only place you will be able to get thos achievement is in the Dark Carnival campaign in Left 4 Dead 2. Do NOT shoot or use a melee weapon on the clowns when you trying to get this or you will kill them.
Instead, what you need to do is repeatedly shove the clowns back. It doesn't matter how many times you do that to a clown. It all counts towards the achievement.

Achievement: Using a molotov, light a Clown on fire that is leading at least 10 common infected.
It would be easiest to try to get this achievement when there is a horde. It might be hard to get as one of the other Survivors could kill the clown before you are able to light it on fire.
