Andre Agassi has been drawn to tennis since he was a boy, but on Sunday he'll be a caricature of himself when he voices his cartoon self on "The Simpsons," along with Pete Sampras and Venus and Serena Williams. Agassi, 30, who just successfully defended his Australian Open title (his third win), said he has always enjoyed the show. "I kinda saw the likeness and I can't honestly say I'm proud of my appearance there," he told PEOPLE.com, laughing a little, "but I guess, you know, when I'm standing next to Homer and Bart I look a little better." On the more serious side of his non-tennis life, Agassi has given his name to a $4.1 million school for underprivileged children to be built in his Las Vegas hometown and funded by the federal government, the state of Nevada and Agassi's own foundation (which also created the nearby Boys and Girls Club). The Andre Agassi College Preparatory Academy is scheduled to open for grades 3 to 5 this fall; grades 6 to 12 are planned through 2008. "Without education a child would have nearly no chance," said Agassi, who spent his teen years playing tennis and never attended college. Now if he could only get Bart a scholarship.
