I actually heard one yesterday.
Our dog (7 month old Sprocker) is very very bouncy and energetic. Whilst out walking, we let the dog off the lead, as always (good recall), and suddenly, over the hill came a young-ish couple and a very old labrador. Our dog bounded over to them and started jumping about, and then I heard it - the tinkly little laugh - "Oh, he's lively isn't he?"
Which instantly I knew meant -"get him OFF!"
We called our dog immediately and he came.
AIBU to think that this was a true interpretation of the TLL??
