Local Starbucks customers in Boston got the surprise of their life on St. Patrick's Day, when an unidentified man walked into the famous coffee hot spot and reportedly threw a huge chunk of money in the air.

"A gentleman walked in and yelled three times, 'I'm rich, I'm rich, I'm rich!' ... and threw a bunch of money," said customer Tara Mardigan, who witnessed the scene. "Everybody was just stunned."

According to the news report, nobody was able to identify the man, as he left immediately after the incident.

"He just walked out so calm, like nothing happened," said Branden Lapia, another eyewitness.

So what happened to the money, which totaled $100 in $1 bills? The report says there are plans for it to be donated to relief efforts in Japan.
