Sky's the limit
Sean "Diddy" Combs and Shawn "Jay-Z" Carter are among the heavyweights heaping praise on the late Christopher Wallace in "Biggie: The Life of Notorious B.I.G.," a documentary that argues the performer's biggest sin was cheating on wife Faith Evans. Skeptics may raise an eyebrow, but there's no arguing over his rap skills, which are generously sampled.

Class clowns from different schools take center stage in two marathons that should get you through Labor Day. "Welcome Back, Kotter" (4 a.m., Antenna TV) takes you back to John Travolta's school days while "Broad City" (8 a.m., Comedy Central) proves that grown-ups can be just as childish as any Sweathog. All 30 episodes of the sitcom, which returns Sept. 13, will be shown.
King of comedy
Paying homage to Jerry Lewis, who died last month, is a tall order, but TCM has assembled a smart tribute that opens with 1963's "The Nutty Professor" and continues with "The King of Comedy," "The Stooge," "The Bellboy" and "The Disorderly Orderly." It's hard to think of a better slate to represent the comic's talent.
