LOL yes, the things you can do with the console in Morrowind are pretty fun.
I overused the console in Morrowind and Oblivion. In Morrowind I set my speed to extremely high, took one step, and... the game froze.
Then there were other times where I set my speed to high and got infinite water walking and then just ran over the ocean for a while to see if anything happened.
In Oblivion, I used to use TCL (which lets you walk through walls/floors/float in the air) and went extremely high over a town and then just fell. With God Mode on, of course.
