The King's Speech

this is an actual conversation i had with a co-worker:

me: you know people that are just born into filthy rich families?
co-worker: yeah tell me about it
me: i noticed there are two types
co-worker: oh really?
me: yeah. those that take full advantage of their parent's status/money and act like complete snobs
co-worker: and the other...?
me: those that are really... um...

(10 second pause)

me: ... oh god.. what's the word...

(co-worker looking intently at me)

me: ... low to ground...?

co-worker: um, you mean, DOWN TO EARTH?

me: oh my god, yes!

co-worker: did you just seriously say low to ground. what's wrong with you? your brain trying to come up with synonyms or something??

(both of us dying in laughter)

i don't know if it's because i just turned 24 a few days ago but i'm experiencing some strange phenomenon between my brain and my speech these days.
