you are right an anecdote is indeed a short interesting account or a humorous incident. here is a possible anecdote that fits your criteria but keep in mind that since we have no way of observing dinosaurs and their possible interactions with ice cream my anecdote is just going to be a fictitious story designed to induce laughter and should not be taken as real.

John the triceratops had just gotten hold of some ice cream. He had heard that ice cream can cause "brain-freeze" and he wished that this would not happen to him. He indeed did not get "brain-freeze" because he had forgotten he had no arms to hold the cone and it fell to the floor uneaten.
