President Barack Obama used 22 commemorative pens to sign healthcare reform into law Tuesday, which is four more than he would need to write every letter of his full name, Barack Hussein Obama, with a separate pen. Obama's traditional signature does not include his middle name, however, so it's unlikely he would have written it on the bill.

As he methodically signed the landmark bill one letter at a time, the left-handed president looked up at the crowd and said, "I hadn't practiced this."

Rep. John Dingell (D-Mich.), the longest serving member of the House and a witness to scores of presidential signings, reassured him,"You're doing fine, Mr. President."
