Snowmobiles.

There's this advert for Vodafone which says "The internet is now mobile", written in cables that have been ripped out of the wall. They have frayed wires & connector plugs on them. But the cable spelling the I of "is" is white and the background of the poster is yellow - so the I is hardly visible. So I keep reading the advert as "The internet snow mobile", and thinking "That's pretty cool. I wonder what the internet snow mobile is?".
