Jesse Eisenberg is voluntarily planning to donate one of his kidneys to a complete stranger in less than two months. "I'm actually donating my kidney in six weeks. I really am," Eisenberg, 42, said on the Thursday, October 30, episode of the Today show, after helping the morning show set up its blood drive. "I don't know why. I got bitten by the blood donation bug [and] I love it. I'm doing an altruistic donation [in] mid-December. I'm so excited to do it.
