My favorite is Matthew 5.

2 He sez hai and he teaches teh kittehs, he sez:3 Cheezburgrz 4 teh n00b kittehs, theys can has teh Ceiling.
4 Cheezburgrz 4 teh sad kittehs, theys can has petting.

27 Ceiling Cat iz liek “no buttsecks!!1!1 bad kittehz!” 28 but im liek “wtf? im in ur brain, watching u think about it” 29 if ur eye sins, scratch it out with ur claws, or uz betr off in trashcan, srsly.

37 “ya rly:=ya rly; no wai:=no wai. else evil kitteh.”
