I posted several dozen of them in Memes14 starting at post >>581317 and IBOR War Room #8 starting at post >>581508 . Other anons have also posted many IBOR memes there. Can you use them?
An anon posted some possibilties
if comb your hair is metaphorical
lice = bugs (hidden microphones)
nano dust = can't get rid of by combing
Or they were observing Snowden by satellite and his hair was actually messed up at the time Q taunted him.
Or all these possibilities at once.
