My job at the helium factory was great

This joke, centered around a job at a helium factory, is a fantastic example of humor built on clever wordplay. The setup leads us to expect a common workplace complaint, perhaps about a demanding boss or boring tasks. When the punchline arrives, it masterfully twists our expectations by playing on the double meaning of the word "tone."

Normally, when someone refuses to be spoken to "in that tone," we imagine a rude, disrespectful, or condescending manner of speaking. It's about attitude. But the context of a helium factory immediately brings to mind the gas's famous effect: making voices high-pitched and squeaky. So, the "tone" in question isn't about disrespect at all, but literally about the altered, high frequency of the speaker's voice after inhaling too much of the noble gas.

The humor springs from this unexpected literal interpretation, turning a relatable complaint about communication into an absurd scenario. It's a brilliant pun that relies on our shared knowledge of helium's vocal effects, delivering a lighthearted twist on a common idiom and making us giggle at the sheer silliness of it all.
