<human>: This took place probably 10+ years ago but I will never forget...
     In my area it is commonly  known that there is(was) a one armed stripper  who would do all sorts of pole tricks with her stump, and sometimes people would seek out a performance by the one armed stripper for laughs(fucked up, I know).  I had personally never had the privilege of seeing her dance.
     Anyway I'm at a buddies house who was having a bunch if people over, many who I had never met.  At one point in the evening a pretty good looking girl and I struck up conversation.  We were hitting it off and she requested that I drive her to the store to pick up more beer.  We bought the beer, and on the way back she mentioned that she has worked at many nudie bars in the area... With all her flirting I thought I was getting laid for sure.  That is until she mentioned a certain establishment she had recently been working.  I instantly recalled that the one armed stripper was known to dance there from time to time.  For some reason, I started laughing and then  I very obnoxiously asked her "No shit! Do you know that fuckin' one armed stripper!?"
She gave me a ice cold stare and replied " yeah... that's my sister you fucking asshole".  I was caught of guard and didn't know what to say so we rode the last mile in complete silence.   Back at the party she kept giving me dirty looks and I overheard tell several of her friends that she wanted to "punch me in the fucking face".  I told the guys what happened and they thought it was funny as shit, but I still felt like an asshole.

Can you condense the text into a few key points?
<bot>: asked a girl if she knew the "fuckin' one armed stripper" and it turned out to be her sister.
