No it isn't, you'd need at least 6-8 hours. At least. It's quite unhealthy to become sleep deprived. Also it's important to keep a healthy biorithm and go to sleep roughly the same time every day. Unless you have a special mutation in the hDEC2 or ADRB1 gene that allows you to sleep 4-6 hours a day and feel totally energized.
No, that isn't the joke,
#1: you said you needed that, and
#2: the joke of the meme is the last one with 8 hours of sleep in 2 hours.
Better luck next time for making a joke about sleep deprivation, because it's not funny at all.
