Dumbest Survey Question Ever

I was completing an on-line survey yesterday and came across this gem:

"In the past six months, how many of your on-line purchases were made on-line?"

What?!

If I'd ordered off-line &mdash say, via phone or mail &mdash that wouldn't be an on-line purchase, now would it. Do I have the option of ordering on-line any way other than being on-line?

But wait: it gets worse. I didn't have the option of answering "All of them" or, more appropriately: "All. Duh!" I had to choose "Nearly all" over "Most of them," "About half," and so on.

They really shouldn't let Wal-martians write surveys.
