Who am I?

My name is Andy Green, I am a student at the University of Northern Iowa.
When my grandfather passed away in 2004, I received a Mr. Potato Head that had been sitting on his shelf. Instead of just letting it sit on my shelf, I started taking him with me when I traveled and take pictures of him in front of different famous locations.
In February of 2007, Barack Obama came to Waterloo to announce his canidacy for President of the United States. I went to the event with Mr. Potato Head and fought through a crowd to get a picture of Senator Obama with my potato. Sen. Obama was very kind and took the picture. That night I thought to myself, all these canidates will be in Iowa and in my area, I want to get them all. And that is exactly what I did. Every canidate posed with Mr. Potato Head, even Hillary Clinton. Well, every one except Joe Biden, who; "Does not take pictures with funny hats and funny toys." I even got Bill Clinton to pose with it.
I am now in the process of getting pictures of him in front of all 51 Capitol Buildings, every Major League Baseball park, the Presidential Gravesites, and the 1000 places to see before you die. Plus anything else I want.
