What kind of murderer has a moral fiber?
A cereal killer.
It's a simple joke... but put me in front of an audience and I'll botch it. I'm a realist. I know that I'm not a good joke teller.
So would it make sense for me to try to joke in my college essay? Nope!! It's not my voice.
The takeaway? Be true to who you are! Your essay will reflect you, and that is what college admission officers really want to hear.
