"I'm hungry !" / "Hi Hungry, I'm dad !"
"A man walks into a bar and says 'Ouch'."
"Why is a raven like a writing desk ? Because there is a 'b' in both and an 'n' in neither."
Those 3 English examples show perfectly why a "universal translator" is something impossible. You CAN translate it, but it will be incomprehensible.
Not convinced ? Here's a French example with a literal translation :
Que dit une maman baleine a son enfant qui fait trop de bruit ?
Cétacé ! (C'est assez)
What does a whale mum say to her child who makes too much noise?
Cetacea! (That's enough) -- Anon Guest
One would think, what with all the diverse languages in the Galactic Alliance, that comedy would not be a shared experience. Those people had not counted on two things: the ability of humans to make fun of themselves, and the ability of other peoples to find humans ridiculous.
Observational comedy, as it turns out, is almost universal.
"You want something manhandled to death, you make sure there's a human around, and then hang a sign that says, 'do not touch'."
Even the humans laughed at that one.
