Do speaker cables need a burn in period?


I have heard some say that speaker cables do need a 'burn in', and some say that its totally BS.
What say you?

Didn't Marx say cable makers will sell the cables that we will hang them with? Their necks will show evidence of burn in.
Marx quotes,

“Time flies like an arrow; fruit flies like a banana.”

“I've had a perfectly wonderful evening. But this wasn't it.”

“I never forget a face, but in your case I'll be glad to make an exception.”
