ACDC 

Possibly one of the most mediocre rock and roll bands in the history of music. While most people who wrote a definition about them consider them to be 'the best band there ever was', popular opinion has once again proven itself to be obsolete...everyone loved Hitler at first, right? But then they all came to their senses. There will come a day when any fans of ACDC will be kicking themselves for their wasted years idolizing them.

ACDC are as boring and annoying as heck.

ACDC 

A lousy Grade Point Average of 2.25 for four courses, consisting of an A, two C's, and a D. If this is your norm, don't plan on going to grad school, or else you'll be taking the HI-GHWAY TO HELL!

Btw, my grades totally suck this semester, an A a C and a D. If I had another class and got a C in it id have ACDC lol. My A was in Computer Repair of course.
