Would You Keep Paul McCartney Waiting?

CNBC's Jim Cramer was bantering with fellow stock market commentator David Faber when Jensen Huang (shown in background) arrived nearly half an hour early for an interview with Cramer.

Jensen Huang and Elon Musk are the rock-starrish two most famous businessmen on the planet (the difference is that they're mobbed by nerdy guys instead of women).

Others who used to hold that lofty position, like Bill Gates and Jeff Bezos, have reduced their roles in the companies that made them centi-billionaires.

It's a sign of Jensen Huang's humility that he patiently waited for Jim Cramer to finish his segment, although Jensen is even busier than normal at this week's Nvidia GTC (GPU Technology Conference) in San Jose.

This blogger's question to Mr. Cramer: would you keep Paul McCartney waiting?
