Lazy halloween costume idea
A vampire pretending to be human
Get a few bits of a vampire costume
Maybe a single really ostentatious piece of costume jewelry
Or maybe a big black cape with scarlet trim
Other than that, wear the blandest, most stereotypically ‘boring human’ clothes you have
Get a bottle of V8, remove the label, apply a new, reasonable-quality label indicating that it’s blood, and then over that put a shitty masking-tape-and-markers label proclaiming it to be V8 again
Occasionally start a sentence with an over-the-top faux Transylvanian accent, then cough and very deliberately start the sentence over in your normal accent
Conspicuously avoid mirrors
Poorly-informed historical reenactor from the future
Get bits from all the costumes you have
Also any sports equipment, formalwear, etc you have lying around
E.g. a toga over a corset and camo pants, a baseball cap underneath a WWI-style Prussian Pickelhaube, and a bow tie.
Also grab at least one sci-fi toy; if anyone complains that it’s from the future, tell them e.g. “I know, I know, American-made laser pistols didn’t have neutron inverters until the late 1930s, but this was the only one I could get on short notice.”
Periodically pick up random objects and start taking into them, then look surprised when nothing happens.
If anyone asks about current events, just start asking about historical reference points that make no sense, e.g. “Remind me, how long has it been since President Sacagawea charged the light brigade with the Zenghouyi Bells?” “Erm, did Italy sink yet or are we still in the Han dynasty?” “How many magnetic monopoles are there in Tshipembe right now?”
A werewolf but it’s not a full moon
Pretty much just dress normally
But if anyone asks if you want to go for a walk, get REALLY EXCITED
Snack on cookies shaped like dog treats
Sniff at people from time to time
If an animal runs by the window, stop and stare at the window for an uncomfortably long period of time
Any time you’re exposed to moonlight, do this:
