Most Helpful Girls
Lotsssssss of food related videos (they're my weakness). There's also quite a few channels I'm subscribed to that basically just react to funny things people send them. It might seem stupid but some of these people are so entertaining that it's actually very enjoyable to watch (examples: Jacksfilms, Alonzo Lerone, Macdoesit)
Most Helpful Guys
Almost exclusively food channels.
Bart's Fish Tales, ChefSteps, Jamie Oliver, TheReportOfTheWeek, HellthyJunkFood, Strictly Dumpling and Best Ever Food Review Show.
I also follow Poppy, h3h3 and some gaming channels that interest me.
Something like "Meat tree" or "Sad man". It has to be strange to entertain.
