These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Memetic Mutation - Several of Eddie's skits have been subject, most frequently "Death Star Canteen". Also, the "Cake or death?" bit.
"I poked a badger with a spoon."
Also "BEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEES!!"
"Covered in bees!"
Older Than They Think - Before there was "Cake or Death" there was "Death or Plumbing", from an earlier performance in which Izzard remarked that the Daleks from Doctor Who had a death ray on one side and a plunger on the other.
