Like Bill Murray, Steve Martin pretty much made his bones by being both funny and up for anything. Take, for instance, his 1976 appearance on The Carol Burnett Show, which Mental Floss just called to our attention. In the clip, below, Martin does his stand-up not for Burnett’s audience of living human beings, but for four dogs that sit on the stage in front of him, lapping up all his puns about poodles, newspapers, and “canned barks.” Just watch out for that dog whistle. Seriously, the whole thing is adorable, and not just because Martin is so damn charming.
