these people came to my school like 5 years ago who were paranormal investigators and they had all these devices and everything. they would randomly play these audio clips that sounded like a retarded kid yawning and then they'd be like OMG, TEH GOWST JEST SAID "gooday sir i'm a ghost, stop recording what i say"
then they'd show pictures with light flares in them and they called them orbs which are clearly ghosts. they needed to get polarizing filters on their lenses and stfu
i hid a boombox under my friend's chair and played the ghostbusters theme song right in the middle of their presentation. the only downside is that i was unable to see the end of the presentation...i was hauled out of the auditorium by some fat teacher
