As they say, there are two rules in improv: Never say no, and never ask why. When another actor asks 'Why?' or says no to something you're suggesting, then it's very clear that they're putting the onus on you, because they're not comfortable with it themselves.
“I'm on so late I'm definitely the last seconds of anyone's attention. So I just want to give them something dumb to laugh at, so they go, 'That's funny,' then fall asleep.”
