Thank Yous Notes

I bought a package of thank you notes the other day.  The packaging says "10 Thank Yous."  This struck me as funny.  As if you would open the package and hear "Thank you" said in 10 different voices; or have 10 sets of just the words "Thank you" fall into your hand.  Would it have been that difficult to label it "10 Thank You Notes"?  :)
