Trying to understand this Miller Lite ad...

I mean, I should give it a shot since it's going to be on every commercial break during the Orioles-Tigers game this afternoon, right?

So this guy is heading off to do Karaoke - and feels compelled to let the convenience store know about it.  Before he goes, however, he needs to buy a six pack of light beer.

1.  Why?  Don't Karaoke bars serve beer?  He clearly doesn't need to drink a few beers before he works up the nerve to sing in front of an audience, since at the drop of a hat he'll belt out a line for a total stranger (who really needs that condescending smirk wiped off his face btw.)  Maybe it's for the audience, which might respond better to his crooning after a few beers?

2.  Am I supposed to think it's charming that the smarmy convenience store guy needs to know what they guy's plans are for the night?  Um, is this an f--ing store or not?  Ask for my ID, give me my change, mind your own g-d damned business, smarmy convenience story monkey.

As for the "let's hear some," um-- no.  Come to the bar and hear me sing there if you want.  I'm not your f--ng trained seal, knob.

3.  If this guy is going to do Karaoke, why would he be at all gobsmacked when a woman comes in during his idiot screeching?  Oh right- because he's not drunk yet?

4.  How is any of this supposed to make me thirsty for watered-down beer?

Meh, no.  I still don't get it.
