"get away you slag" Derek said to Miss Westbrooke on ghost towns
"i would be supprised if you told me you didnt have any negative reversal ectoplasmic conditions" derek to a couple of ladies on ghost towns
i also couldn't beleive when he told a guy when he was doing his doorstep divination part that he could forget calling a plumber or an electrician because it was the spirit world breaking his boiler and he would close the portal and then the guy said well that'll save me alot of money ;D ;D ;D
