The episode earned an Emmy nomination. For a number of episodes, Letterman continued to crack jokes about his bypass, including saying, "Bypass surgery: it's when doctors surgically create new blood flow to your heart. A bypass is what happened to me when I didn't get "The Tonight Show!" It's a whole different thing." In a later running gag he lobbied his home state of Indiana to rename the freeway circling Indianapolis (I-465) "The David Letterman Bypass". He also featured a montage of faux news coverage of his bypass surgery, which included a clip of Letterman's heart for sale on the Home Shopping Network. Letterman became friends with his doctors and nurses. In 2008, a "Rolling Stone" interview stated he hosted a doctor and nurse who'd helped perform the emergency quintuple-bypass heart surgery that saved his life in 2000. 'These are people who were complete strangers when they opened my chest,' he says. 'And now, eight years later, they're among my best friends.' Additionally, Letterman invited the band Foo Fighters to play "Everlong", introducing them as "my favorite band, playing my favorite song." During Letterman's last show, on which Foo Fighters appeared, Letterman said that Foo Fighters had been in the middle of a South American tour which they canceled to come play on his comeback episode. Letterman again handed over the reins of the show to several guest hosts (including Bill Cosby, Brad Garrett, Whoopi Goldberg, Elvis Costello, John McEnroe, Vince Vaughn, Will Ferrell, Bonnie Hunt, Luke Wilson, and bandleader Paul Shaffer) in February 2003, when he was diagnosed with a severe case of shingles. Later that year, Letterman made regular use of guest hosts—including Tom Arnold and Kelsey Grammer—for new shows broadcast on Fridays. In March 2007, Adam Sandler, who had been scheduled to be the lead guest, served as a guest host while Letterman was ill with a stomach virus. In March 2002, as Letterman's contract with CBS neared expiration, ABC offered him the time slot for long-running news program "Nightline" with Ted Koppel. Letterman was interested as he believed he could never match Jay Leno's ratings at CBS due to Letterman's complaint of weaker lead-ins from the network's late local news programs, but was reluctant to replace Koppel. Letterman addressed his decision to re-sign on the air, stating that he was content at CBS and that he had great respect for Koppel.
