Quoted:
Please knock it off with the whole "you hurt my daughter, i kill you" crap. comes across as weak.

Was talking on phone with girl I had one date with, but respect enough for more. Unbeknownst to me, her family is there and her dad asks to speak with me. Then proceeds with the whole 'what do you want with my baby girl" tripe... and you absolutely cannot say it over the phone and be convincing, you are not Liam Neeson.

I was polite but even if he was joking like he claimed at the end of the talk, he still sounds like a douchebag.

The fact he's not a Frank Sinatra fan didn't help him either.  

I don't blame him for being protective, I would be the same but there are better ways of going about it. For starters, this should have been done in person.

Rant off..
