"Days of Thrills and Laughter" opens with what the narrator calls "the first double-feature title" in which the opening credits are shown on the right-hand side of the screen while an excerpt from the 1922 Snub Pollard comedy "The Movies" is displayed on the left.
When the credit for the film's composer-conductor appears, the narrator calls out, "Hold it!" and both sides of the frame freeze. "OK, bring up that name," intones the narrator, as "Jack Shaindlin" expands to nearly the full width of the frame. The narrator declares, "That's enough!," the name shrinks back to its original size, and the movie starts up again, with the narrator explaining, "Sorry, folks, it's in his contract."
At the end of the credits sequence, the movie freezes once again so producer-writer Robert Youngson's name can do a cartwheel while expanding to large size. To which the narrator exclaims, "What a showoff! Take Youngson down - all the way down!" as the name shrinks and disappears.
