Joe Biden has a good sense of humor about himself: (although I don't know any reason why men should not 'plug in', if desired. In my opinion, baldness is not an issue affecting value but some men evidently do)

"Along with Biden, the ranks of the senatorial plugged-in included the late Wisconsin Democratic Sen. William Proxmire — who served from 1957 to 1989 — and South Carolina Republican Strom Thurmond, whose fiery orange plugs stayed in until he died in 2003 at the age of 100.

"At Thurmond's 90th birthday party, Biden found a patch of common ground. "When I came to the Senate in '72, you were 70," he said. "And I want to tell you I resent any reference to your hair. You have been an inspiration to me in so many ways."
