It's all in the presentation

So this morning I noticed that Henry's nails were way too long and way too dirty so I went to get his nail clippers. I came back downstairs and announced that it was time to clip his nails.

Henry - "I don't want you to cut my nails"
Mom - "Girls really like boys with short, clean nails"
Henry - "Do really pretty girls like cut nails?"
Mom - "Yes, especially the pretty girls"

So he climbed in my lap and let me cut them. Why didn't I think of this strategy sooner?
