The rules are simple, pick something banal, the more banal the better, anything will do, the content is unimportnant it just needs to be imbued with some vagueness, some uncertainty as to what you are saying - "The cloud knows not where he is going, nor will he get there" - say it with complete authority, say it very very slowly, almost comically so, putting long pauses between odd couplings of words and place emphasis on where you would not expect emphasis:
The cloud . . .
Knows not W_h_e_r_e (really drag this word out). . .
he ? is going . . . (try and make 'he' sound like a question in it's own right)
Nor . . .
. . .
Will he get there. (always say the final word very very quietly, almost whisper it)
