I am become bass, destroyer of riffs

I have had larger pals get upset when unable to sleep at night because there was no accessible bed. Oddly enough though, if I slept through the night it wouldn't happen. I think because there was enough "nighttime" for them to get upset. Of course ymmv but might be worth throwing one or two outside to be safe!

What's a CD grandpa?

I don't think you commented on what you thought you did

As an American who loves Taskmaster, I too was confused haha
