I accept a duel against your horse only. let me know when.
Anytime. My horse will wear full plate armor and fight running backwards with a lance sticking out of its rear end.
Should you lose (and you should), you shall henceforth be named BaleOHorse.
In the unlikely even that my proud steed should not prevail, it will surrender its title "Earl of Dynad.onkey" and its favorite fodder bag to you.
