Alternate title: "Secret Agent."
"Ready for the Betty's" is one of only a couple Episodes in the series, "Phineas & Ferb", that isn't in the rotation of re·runs that are shown today. Not under the title shown above, or under the other title, "Secret Agent".
The truck that honks as it passes the tour bus says "The Amazing Folding Mattress Company" on the side.
The episode, "Ready for The Bettys" was taken off the air for a while because a real-life band also called The Bettys that the creators didn't know about while making the episode thought they were plagiarizing them. "The Flying Fishmonger" and "Phineas and Ferb Musical Cliptastic Countdown" were also taken of the air due to the former being paired with the episode and the latter having the song of the same name featured at #10 in the countdown.
