Used to party until daylight Was creeping o'er the eastern skies Danced all night and slept all morning But now I've come to realize I'm getting tired 'round eleven And still I'm looking for a nap When did I become the old guy And can I get that young guy back? When did I become the old guy? Yesterday I was a pup Thought it'd be that way forever Then this old dog grew on up Faster than I had expected In the blinking of an eye I was only getting started When did I become the old guy? I used to drink beer by the pitcher Had no problem the next day Ate whatever junk I wanted And never would gain weight Now I'm subbing shakes for breakfast And eat raw veggies for a snack When did I become the old guy And can I get that young guy back? When did I become the old guy? Yesterday I was a pup Thought it'd be that way forever Then this old dog grew on up Faster than I had expected In the blinking of an eye I was only getting started When did I become the old guy? Always felt like I was clueless Now they're coming for advice They ask me about my marriage How my kids grew up so nice But they weren't there when we were screaming Frustrated out of our damn minds When did I become the old guy Guess that young guy turned out fine When did I become the old guy? Yesterday I was a pup Thought it'd be that way forever Then this old dog grew on up Faster than I had expected In the blinking of an eye I was only getting started When did I become the old guy? I was only getting started When did I become the old guy?
