This is a boss one, probably pretty common, but I found it hilarious. She's working with these picture files and she calls me over to help her. The file she started with was about 2/3 of an inch square, and she's blowing it up to an entire page. She calls me over to "fix it" because "it looks all crappy."
I tell her that at the size she's starting with there's not a whole lot she can do, the resolution is going to be pretty bad.
She looks at me and says, "Isn't there a button that gives it more resolution?"
