Band names

"Buddha spent his whole life trying to reach Nirvana."
"Yeah, if only he'd lived in the 1990s."
"Why?"
"Well, one call to Geffen Records would have done the trick."
"Good point. But do you think Kurt Cobain would make the time to meet the Buddha? I'm sure his agent wouldn't allow it. 'I canceled your lunch with the Buddha, darling. He is much too touchy-feely. Could damage your image.'"
"OK, so not Kurt Cobain, but someone would meet him. Like Dave Grohl."
"Oh yeah, he was in Nirvana, too. Before he joined the Foo Fighters."
"That's right. What does that guy have against Foo anyway?"
"What is Foo anyway?"
"I don't care. But he best leave that Foo alone if he knows what's good for him."
"How did we get to this topic?"
"Waiter!"
