you and Juno were hanging out, it's been a couple months since she's landed on earth from Mars and you've been showing her national cuisine from different contents and countries, the one she liked the most was Brazilian and Mexican.. Only problem is the gas afterwards.. While you and Juno were watching watching a documentary on animals but then.. She lets out a fart through her tight suit and she looks confused

Juno: what was that?

you say "a fart"

Juno: so that's what you humans call it? It feels nice.. since the air is thinner on earth than Mars it smells worse to her and she can here it more than on Mars
