I've totally done that too. I once saw that "Good Will Hunting" was airing on USA Network, and thought, Cool! They're showing Foster's on USA Network! Darn, it's an "L" not a "T".
Here's a new one I'm guilty of just this week. I found a red pen with white lettering on it. The pen said "Mac's Towing". I took a permanent marker and colored the entire top of the pen so, mixed with the red, it looked brown-ish. I then scratched off the red paint from the word "Towing" so that it was a splotchy white. And then I called it my "Mac Pen".
