It's A Puzzle

Isn't it a puzzle that an is'll be a was?
 In the middle of a muddle it'll trickle to a flood
 Don't let the rain go and drizzle on your muzzle
 It's a puzzle that an is'll be a was
 Just a puzzle that an is'll be a was
 Do you want to know why I want to go to Idaho?
 I gotta go to Idaho. I hadn't been there
 It's excuses and saying it's no use
 That keeps us from getting anywhere
 Oh, isn't it a puzzle that an is'll be a was?
 In the middle of a muddle it'll trickle to a flood
 Don't let the rain go and drizzle on your muzzle
 It's a puzzle that an is'll be a was
 Just a puzzle that an is'll be a was
 Is is 'till it isn't and then it was
 Was once was an is, back when it was
 You can't be counting every second
 But if you make sure that every second counts
 Maybe might be an is in a second
 Have you figured that out?
