This is not how you do a parody Robot Chicken.
Stop it.
You need to make fun of the source material for it to be funny.
Hell, TF2 literally writes itself with just the characters themselves.
Why'd this skit have to include something totally unrelated? Why.
God damn. You had potential, and you decide to play it safe.
I'm not saying the skit is bad, but it has nothing to do with TF2. It's just, well, boring.
Although it could have ended far, FAR worse.
