Not a moped I mean a proper motorbike.
Quick true story (I hope I can get away with this)
The French just happened to capture a British Major. An officer brought the Major to the French general for interrogation.
The French general began ridiculing the Major for wearing "that stupid red tunic."
The French general said, "Why to you wear that red uniform, it makes it easy for us to shoot you."
The British major replied, "If I do get wounded, the blood will not show, and my soldiers will not get scared."
The French general said, "That is a very good idea."
And that's why the French Officers took to wearing brown trousers.
