Meet Regis Philbin, hedge fund intern.

Taking up a recent offer for a summer internship at David Einhorn's Greenlight Capital, television legend Philbin revealed what his day was like Tuesday on CNBC's "Fast Money."



"Yes, so I went up to the David Einhorn offices, met everybody," he said. "Happens to be a very nice guy. We had a long, long talk. And I tell you how it ended: They thought I was the best summer intern they ever had."

Last week, Einhorn said on air that he had been impressed by one of Philbin's winning stock picks and offered the former TV show host an internship.
