Wow. The scary thing is that there are probably dozens, if not hundreds, of large holiday lighting schemes that may also be set up like this.

It's really shocking (pardon the pun) that people still don't understand that 110 is dangerous, be it a shock hazard or fire hazard, or both.

Heh, wow, ten plugs into an extension cord... at my house 3 is a max... I think the lights say you can only plug X number together safely...
