I was saying my brother's name over and over again a few years back (because it annoys him, and is therefore funny) and I therefore began questioning whether it was really his name, and whether it was really a name at all.
We once had to write out a table in biology, with one column just including the word 'brain' 20 times (I'm not sure why). The appearance of the word still confuses me, as does the sound of it when said repeatedly.
'Plenty'... It's a dark one. Say it over and over and then it'll dawn upon you, you'll be like, "WTH am I even saying? What is this? Ahhh!". That's when step two kicks in and you're like, "The Illuminati made this! Bloody Illuminati! Stupid... always tryna control us! ".
