Occam's razor.

[Sorrano]

Enrique, I think it might be funny to give a literal translation of the Spanish expression "No le busquemos pelos al huevo" ( = 'let's not split hairs'). So, a literal translation gives : 'Let's not look for hairs in our egg'. Love it!

Plumas might bother me even more. In Europe, do you use the expression, tomar pelo, when giving someone a hard time?

[Quijote]

Actually, the French also have a similar expression involving hair : "couper les cheaveux en quatre" = 'cutting hairs into quarters'. Other expressions in Balzac's language are "chercher la petite bête" = 'looking for a little animal' and more vulgar : "enculer les mouches" = 'bugg**ing flies' !
Thought you would all like to know that. Vive les langues, vive les différences !

"Pulling somebody's leg", I would have said.

In Colombia they do say "estoy tomando pelo", not sure if they do further South or in Europe. It's a common dicho, there.

Tomarle el pelo a alguien. Literalmente, take somebody's hair. Used as far south as Argentina. E.g., are you taking my hair?
