The laudanum in Season 2 Episode 3 has a Terry Pratchett easter egg on it! :)
It reads "Guaranteed by C.M.O.T Dibbler & Co. CHEMISTS". C.M.O.T Dibbler (Cut-Me-Own-Throat Dibbler) is a character from Terry's Discworld featuring in many books :).
"C.M.O.T. Dibbler liked to describe himself as a merchant adventurer; everyone else liked to describe him as an itinerant pedlar whose money-making schemes were always let down by some small but vital flaw, such as trying to sell things he didn’t own or which didn’t work or, sometimes, didn’t even exist." - Reaper Man
"‘Anti-dragon cream. Personal guarantee: if you’re incinerated you get your money back, no quibble.’ 'What you’re saying,’ said Vimes slowly, 'if I understand the wording correctly, is that if I am baked alive by the dragon you’ll return the money?’ 'Upon personal application,’ said Cut-Me-Own-Throat." - Guards! Guards!
“Angua picked out the bottle and looked at the label. "C.M.O.T. Dibbler's Genuine Authentic Soggy Mountain Dew," she read. "He's going to die! It says, 'One hundred and fifty per cent proof'!" "Nah, that's just old Dibbler's advertising," said Nobby. "It ain't got no proof. Just circumstantial evidence.” - Men at Arms
