Neil Patrick Harris Surprises Mary Hart at ET

By
In the latest in a series of celebrity surprises, showbiz veteran Neil Patrick Harris surprised Mary Hart on the ET stage.
The "How I Met Your Mother" star brought Mary 29 yellow tulips -- one for each year that she has hosted "Entertainment Tonight."
"I can not believe that you're leaving, what's happening? You have been involved in ET for as long as I've been watching television and you haven't aged a day," Neil enthused.
Last week, both Michael Douglas and Regis Philbin paid surprise visits to Mary, who marks her last day at ET this Friday, May 20.
