If you had access to a time machine you could travel to December 31st, 2011 and eat a rice omelette with nacho chip cat ears at the first ever Science Adventure Series live event and one-day limited Steins;Gate Cafe in Ginza, Tokyo.
Or if that doesn't look particularly appetizing, you could take Faris out for a day o̶n̶ ̶t̶h̶e̶ ̶t̶o̶w̶n̶ at Comiket. There are consequences for changing such timelines, of course, but what's the problem with a little harmless fun?
