Boston Celtics owner Wyc Grousbeck was so hyped during Game 5 of the Eastern Conference Finals against the Miami Heat on Friday that he started to smack the glass in front of him in excitement.

Take a look at the hilarious moment:

COVID-19 has forced the NBA to take every precaution necessary down in Orlando, Florida at the Walt Disney World bubble. The league deserves so much credit, as there have been zero positive COVID-19 tests since the games started in July.

Wyc Grousbeck has been Governor, Managing Partner and CEO of the Celtics since he bought the team in 2002. Boston won the 2008 title over the Los Angeles Lakers, giving the franchise championship No. 17, the most in NBA history.

Grousbeck and his Celtics are hoping they can replicate that success once again down in Orlando.
