Why?

When Nate was an undergrad at the U he had a Hungarian professor.  Nate worked closely with this professor on a research project and so he got to know him well.  This professor would often say to Nate, "I would like to point out..." and then he'd finish the sentence with an observation, usually very blunt and often about Nate's grades.

Nate would come home and tell stories about this professor and he'd quote the things he pointed out in a heavy Hungarian accent.  And so a tradition was born in our family.  "I would like to point out...!"
