The basketball great and his "Smallfoot" co-star, Channing Tatum, performed a series of outrageous dares, courtesy of Ellen. For each of the dares the guys completed successfully, the comedian pledged to donate $10,000 to I Promise on behalf of Walmart.
"They'd like to give your school some money, but you're gonna have to earn it," Ellen told her guests.
The first dare involved the new Lakers star taking a very large shot of tequila with no hands, which he completed successfully. The second dare involved the "Magic Mike" star doing his "best sexy crawl" across the stage, which he also completed successfully.
With $20,000 in the bank, Ellen upped the stakes. She blindfolded LeBron and forced him to lick a mystery item -- a kiwi -- which he guessed correctly.
"Listen, the first thing that came to mind -- I thought it was an ass," he said. "And I was like, 'Ellen wouldn't do that to me.'"
