Everyone loves Bob Marley.  More importantly girls love Bob Marley.  So if are going to an event where you may actually meet women you might consider opting away from the Star Trek shirt and more towards something they can relate to, like this shirt.  

His first name was actually Nesta.  Robert was his middle name.  He is actually from Jamaica, and had a total of 11 children from assorted women.  I guess he knew what he was doing.  I think his music is cool, but don't listen to it a lot while driving as I don't want to die in a car wreck with Bob Marley music as my death theme.  Yes, this is something I worry about.
