Though it's one of Peppy Hare's lesser quotes (I much prefer "Use the boost to get through!"), the phrase "Do a barrel roll!" has seen a steady rise in popularity, and it's now an undeniable part of gaming culture. How bad is it? Well, just search Google for "do a barrel roll" and you'll see for yourself.

There's a lesson here: don't underestimate the power and influence of a generation of people who 1) grew up owning a Nintendo 64, and 2) love repeating things that they heard in video games. Sadly, searching Google for "What is a man?" does not immediately bring up the definition I wanted. Fix that, Google.
