They're possibly people of above-average stature

We've now got a VPN working, to establish easy access to things as if we were in the UK. One thing the girls like is watching what they call "funny videos" on Youtube. This means things like "Agadoo" with Black Lace dancing with a lady dressed in a pineapple costume. Or "Baggy Trousers" where Madness's flying saxophonist always gets them laughing. The also like more recent stuff like Katy Perry's Hot and Cold and Lady Gaga's Bad Romance... and anything by Alvin and the Chipmunks. The latest "discovery" is They Might Be Giants, although I gather that anyone who watches Conan will have seen them a lot. The girls particularly like Never go to Work and One dozen Monkeys.
