"We're improvising a lot of this, which amazes people"

In this quote, Tom Bergeron is revealing his surprise at the reality that they are improvising a lot of what they are doing. This suggests that they are not following a stringent script or plan, however rather making things up as they go along. This can be a difficult job, specifically in front of an audience, but it appears to amaze people. This could be since improvisation requires fast thinking, imagination, and the capability to adjust to unanticipated circumstances. It also adds an element of spontaneity and unpredictability, which can be exciting for both the entertainers and the audience.
