Hotel in Georgia. Printer on the network. I was able to print from it since it was on the network exposed. I was able to gain admin access by ARP poisoning the network. Then after that all I did was keep printing to the printer and confusing it's task until it crashed then the admins had to check the log. But, I had ARP poisoned the network so their login was picked up by me. I promptly logged in and changed the admin password to... password
Yep. Oh and of course they gave me permission to do this. (;
