Humberto: Hi ladies, how's it goin'? You girls wanna hang out?
Girl 1: No, we have to do stuff
Humberto: Well what if I told you I had the "What are you trying to prove" achievement?
Girl 2: What the hell is that?
Humberto: It's something special from Left 4 Dead, just like the two of you.
Girls: laugh and walk away
Humberto: Slowly dies inside
Random guy watching: That's the saddest thing I've ever seen. What an achievement scrub.
