I had staff that used to talk over me and each other. Drove me batshit, but they were good employees. One day, i couldn’t get my words out for being interrupted, when i suddenly grabbed my sea otter tape dispenser off my desk and proclaimed “I have the talking otter! Let me finish speaking!”

They were so thrown off by the absurdity that it worked! I got my thought out, then handed the Talking Otter to the next person who had comments. From then on, if they got unruly, I’d say “do I have to go get the otter?”
