You don’t have to be polite or sneaky in improv like we often are in life. If a character asks if you stole that money and you did, your human instinct is probably to deny it. In improv, it moves the scene along a lot more quickly if you’re brutally honest. “Yes, I stole the money, and I’m using it to start a thieves’ guild.” The more clear you are in a scene, the more helpful you’re being to your scene partner, and brutal honesty is about as clear as communication comes. It’s also an awful lot of fun to be unapologetically honest. Try it!
