11 Year Old Catches 27 Year Old Smithsonian Mistake

Thank you letter then misspells the kid's name

"ALLEGAN, Mich. - Is fifth-grader Kenton Stufflebeam smarter than the Smithsonian?
The 11-year-old boy, who lives in Allegan but attends Alamo Elementary School near Kalamazoo, went with his family during winter break to the Smithsonian Institution's National Museum of Natural History in Washington.
Since it opened in 1981, millions of people have paraded past the museum's Tower of Time, a display involving prehistoric time. Not one visitor had reported anything amiss with the exhibit until Kenton noticed that a notation, in bold lettering, identified the Precambrian as an era.

So Kevin Stufflebeam took his son to the museum's information desk to report Kenton's concern on a comment form. Last week, the boy received a letter from the museum acknowledging that his observation was "spot on."
"The Precambrian is a dimensionless unit of time, which embraces all the time between the origin of Earth and the beginning of the Cambrian Period of geologic time," the letter says.

Excited as he was to receive the correspondence from museum officials, he couldn't help but point out that it was addressed to Kenton Slufflebeam."
