At first i wasn't sure but she's grown on me week by week and there's something i find infinitely likeable about her, from her wacky clothes to the horror shows she puts on with Mario in the bath. I like Lisa and I'm ready to stand up and be counted, join me!

I agree!

Lisa is so strange and wrong in so many ways, it makes her right.

I worked out last night what it is Mario and Lisa remind me of with there seemingly separate life in the house to the others.

Have you seen Muppets Treasure Island? They are like the rats who take a cruise on the pirate ship. Whilst the Pirates are going about finding Treasure, the rats are dining out, sunbathing and having fun.
In the house, most HMs are squabbling, arguing or taking part in childish games. Meanwhile Mario and Lisa will be exercising, rubbing oil into each other (EURGH!) talking about the others or sleeping lol
