Wishing upon an angel

Little Jimmy was laying about on a hill in the middle of a meadow on a warm spring day. Puffy white clouds rolled by and he pondered their shape.
Soon, he began to think about Angels.
"ANGELS? Are you really there?" Jimmy said out loud.
To his astonishment an angel's voice came from the clouds. "Yes, Jimmy? What can I do for you?"
Seizing the opportunity, Jimmy asked, " What is a million years like to you?"
Knowing that Jimmy could not understand the concept of infinity, the Angel responded in a manner to which Jimmy could relate. "A million years to me, Jimmy, is like a minute."
"Oh," said Jimmy. "Well, then, what's a million dollars like to you?"
"A million dollars to me, Jimmy, is like a penny."
"Wow!" remarked Jimmy, getting an idea. "You're so generous...can I have one of your pennies?"
The angel replied, "Sure thing, Jimmy! Just a minute."
