The Rodeo is broken! Devs please fix it...

Those highscores were achieved using a glitch/bug of the flash player. Basically, if you right-clicked on the screen, the game would have paused, but the timer would have kept going. And when you would have resumed, it would have passed like, for over 10-20 minutes.

But I think that was fixed in the meanwhile.

And also, unless you really care about highscores, getting past 50 seconds is useless, since it doesn't awards extra money.
