Comedy Central’s Jon Stewart razzes ABC’s GMA host George Stephanopoulos over his omnipresence on the network. “Is George Stephanopoulos now on every show on ABC? I wake up at 6 a.m. and he’s there, I go to bed at midnight — he’s still there!” Stewart grumbled on his show last night. “Go home George!”

This morning’s segment had co-host Robin Roberts and Bianna Golodryga laughing on the couch beside Stephanopoulos. The trio, a little while later after some news, moved into a segment on dog tricks, complete with dogs jumping high into the air to catch Frisbees on set. “I just want to say hello over here,” said Stephanopoulos to one of the jumping pooches. “She’s a sweetie.”

Stephanopoulos joked that he’d soon appear on “Lost,” but first remarked on Stewart’s assessment, saying, “Ali would agree with that.” (That would be Ali Wentworth, Stephanopoulos’s wife.)
