Magic Johnson has had enough with the Lakers ... saying the team's performance is so pathetic, he's embarrassed to be associated with the organization.
After Kobe Bryant and the Lake Show got blown out by the Boston Celtics 95 -116 last night, Magic went to Twitter and vented about his ex-team:
"Not sure if I was embarrassed for this Lakers team or embarrassed to be a former Laker, because of how they played against our rivals the Celtics last night."
And to add salt to the wound ... Magic followed up by giving props to Celtics star Kevin Garnett -- "Congrats to Kevin Garnett for scoring over 25,000 career points!"
Somewhere, Larry Bird is smiling.
