It's from then-House Speaker Newt Gingrich's visit to Grandfather, where he met Gerry. Writes Stephen Fletcher:
"Like Newt, Gerry is still alive and kicking. According to the Grandfather Mountain website, 'Even at age 20, Gerry is still very spry and acts like a bear half her age. Even though she is very patient, she does not hesitate to let her keepers know when they aren’t moving fast enough with her very distinctive and adorable moaning.' Perhaps Newt and Gerry are kindred spirits?"
