I'm old enough to remember the jokes surrounding the Mach 3 razors - I think it was MadTV that did a skit where Gillette was adding an extra blade every so often - and it became true - because I'm using razors with 6 blades - 5 on the front and a touch up blade on the other side.
(EDIT) Found the video.

An old relic of the past, I love how the political propaganda then was down to a minimum
