Cry/laugh all the way to the bank

To cry all the way to the bank is to make money, without remorse, at the expense of others. Its alternative form is laugh all the way to the bank. The OED, of all sources, attributes the origin of the ‘cry’ version, seemingly wrongly, to the pianist Liberace in 1956 because Michael Quinion cites a US newspaper that used the expression at least ten years before Liberace did.
