Why a mural at Sky Harbor makes me grateful I am not a frog

This is a photo of a mural that appears on the wall of Phoenix Sky Harbor Int'l Airport at Terminal Two. I'll be publishing more photos from PHX from time to time. Which reminds me of something that happened today. I took a call from someone who wanted to go to the airport, and, unable to locate a piece of paper whilst barreling down the freeway at 67 miles per hour, I wrote the address on the back of my hand, which made me think:

I am so glad that I am not a frog.

For starters, a frog has slimy skin which means he cannot write addresses on the back of his hand. The ink will not stick through all that slime and the pen will end up skipping the next time he wanted to use it. Which means he would have to find a piece of paper to write on. Which brings up the subject of thumbs. A frog does not have thumbs, so it would be very difficult for him to hold a pen in his front hands, and have you ever tried to write a memo with your back feet? I don't even have back feet, so I can imagine that must be very difficult. And what would you do about the phone? A person cradles the phone against his ear and his shoulder while he writes down something, but a frog does not have external ears. It does not even have shoulders, which means it would have to put the phone on "speaker". Can you imagine how embarrassing that would be to call and have a frog put you on speaker phone while he tries to write a memo with his back legs? This is probably why frogs do not get many phone calls. Have you ever called a frog? I didn't think so. And if a frog can't get calls, he probably won't be a very good cab driver.
