BB9UK... Custard Tart-gate gets curiouser and curiouser, so does anyone know who really ate the lot?

BB should keep ALL biscuits under lock & key so we aren't subjected to Mario & Lisa's antics with them!!! EUGH! They are enough to put anyone off dunking a biscuit ever again!!! Hope Mario is up for eviction soon........I have to shut my eyes & block my ears whenever him & Lisa are on screen & my hubby has to let me know when they're offscreen!! lol. He will be scarred for life having to watch them, mind you he shuts his eyes too coz they both gross him out!
