Be careful of a language, even if you know it well.
See, fart translates to speed in Swedish, so I was in France...
And I was living with two nice girls, not gonna go into too much detail about that, but I noticed that the traffic was very wild and wanted to ask about the speed limits.
You guessed it. I literally asked them if they had any "fart limits". God, I don't think that the mistake was ever cleared up.
It's so dumb, because I knew the difference between fart and speed, I just momentarily mixed it up.
Oh yeah, and on a different occasion I managed to pronounce Virginia as vagina in front of my English teacher and the whole class. Yeah, she wasn't too happy about that <.<
I did all of this in toribash. It's on topic and don't question me.
