I want to kill my team leader

In the four years since I joined this company, I have never been as angry as I am today.
If you're going to do a job, at least do it right.
They made such a mess of things that my superior called me and told me to clean it up.
When I asked what the team leader was doing, they said he isn't even picking up his phone...
I told them it would be difficult since I'm out, but they insisted I do it anyway, so I'm ultimately heading out to fix the mess.
I'm actually scared because I feel like I'm going to slap him across the face the moment I see him tomorrow.
Seriously, ah...
