Vow to Vowels

Your grandmother clips them from the gazette
 Piles them by day and Sunday throws out
 Your skill with that paper impress to no end
 Your skill and resistance I can't comprehend
 I never wonder which ones you'll leave blank
 All will be filled once you empty your think tank
 A I to O, 6 more to go-o-o
 A I to O, 5 more to go that you probably know-o -o
 A E I O U, I'm going to use some
 I O U some more, I'm going to lose some
 I made a vow to vowels, I'm going to use some
 I made a vow to vowels, I'm going to lose some
 Filling in crosswords won't make you Walt Mossberg
 But that daily lust will prevent aging rust
 Later the day, the longer it takes
 But everyone knows Will Shortz wants it take way
 Your vocab expanding, your spelling outstanding
 The man of my dreams has a grammar PhD
 A I to O, 4 more to go-o-o
 A I to O, 3 more to go that you probably know-o -o
 A E I O U, I'm going to use some
 I O U some more, I'm going to lose some
 I made a vow to vowels, I'm going to use some
 I made a vow to vowels, I'm going to lose some
 O U. If I can't have U,
 I don't want to, have no other letter.
 A E I O U, I'm going to use some
 I O U some more, I'm going to lose some
 I made a vow to vowels, I'm going to use some
 I made a vow to vowels, I'm going to lose some
