A Billy Joel song which is old but can still touch teens today. It's about struggle and bad luck, but the music with the lyrics is pretty well done. It will make you laugh but maybe also cry...

A reference to the television show "Torchwood", a "Captain Jack" refers to a problem solving technique in which a party seduces every person between themselves and their goal.

Captain Jack Harkness: "The last time I was sentenced to death, I ordered four hyper-vodkas for my breakfast. All a bit of a blur after that... I woke up in bed with both of my executioners. Lovely couple, they stayed in touch! Can't say that about most executioners."
Lucy : I can't believe I blew my professor and only got a "B".

Darcy : Well you know he doesn't even submit the grades. It's the teaching assistant that does that, and you should probably should also have fucked the anorexic guy that sends out the reports if you really cared about your grade.

Lucy : Hey, I don't think I could stand going full "Captain Jack" just for a good E-Sci grade. It's not like it was a core class. Besides, my TA was girl and she wasn't pretty.

Darcy : Sometimes you gotta take one for team Lucy.

Lucy : True that. My main skill is that I'm a massive slut.
