[TOMT][TV SHOW][2000-2020? idk] British lady parodying an educational-sciency show host

It was structured like a popular-science programme, but she would say gibberish stuff while sounding serious, I don't really know how to describe it, but hopefully someone knows what I mean.

I think the host reminded me of Jen from the IT Crowd but I think it was not her so it might be misleading.

Thanks in advance
