Where do you have your best ideas?

At the start of my how to have ideas workshops, I ask where do people have their best ideas. People often say things like running, taking the dog for a walk, talking with friends, first thing in the morning.

Depending on how brave the group is someone will say while on the toilet. 

I must have asked this question to 500 people. And the answer I almost never get is ‘I have best ideas while sitting at my computer’.
