VLAN config error took down the whole office network last Thursday

I was reconfiguring a switch for a new department and accidentally typed 'no vlan 1' instead of 'no vlan 10' on a trunk port. Suddenly nobody could print or access the server for 20 minutes. Has anyone else had a single typo bring their whole network to its knees?

Actually had a lab once where I typed 'no interface vlan 1' instead of just the vlan number and lost all remote access to a switch. Had to drive 45 minutes to the datacenter just to plug in a console cable. Felt pretty dumb that day.
