How high? Higher than Cloud City.
As before, here's a rough translation of the drunk/high textspeak in case you're having trouble.
Npppppp u am nitvhigh I moss dt ey ismt she esting pancakrx: "My N.P.'s (Nurse Practitioner's) uncle held his bat mitzvah this a.m. (it was a morning party) and my gift of edible moss only succeeded in establishing pancreatic ulcers in my host."
Cddk be: "(the) Caterer Dummies Didn't Know; (they) Belayed Eating (the moss)"
Um hoooot hiiiiiifg,,,, wtf I gaac bonr,,,,: "Ultimately, I acted in the manner of a hooooting owl flying hiiiiiigh in the dead of night and covertly escaped the bat mitzvah, my footsteps low to the ground and subtle like a series of commas... my escape was so smooth and fluid that in the middle of it I unexpectedly got a Gigantic And Awesomely Curved Boner."
Hooooonkey: "[racial slur for white people]"
