Should my body and spirit be unable to sustain the seal on the killer joke, the strain on my mind could cause permanent memory loss. The seal is designed such that it would erase the killer joke from my mind before failing, but if it ever reaches that state there wouldn’t be much of “me” left.

Many of you have asked about my relations with the various other ponies around Ponyville, so I’ve been granted clearance to share some files with you. These aren’t ‘official’ Night Guard documentation, but rather my personal notes in case the seal on the killer joke starts to affects my memory. This one here is Hot Blooded Pinkie, whose passionate fire can’t be restrained by the petty coils of physics!
