Although Baseball's gameplay was different in this episode, Numbuh4 seems to be a good baseball player.

Mrs. Beatles' face is seen (albeit briefly) for the second time in this series when she becomes enraged at Numbuh 4 for breaking all her vases.

One of the reporters said Mazel Tov!, which is hebrew, so most likely the reporter is Jewish. The reporters are based on the late Howard Cosell and Harry Carrey.

Chester comes back with a third occupation. First in F.A.S.T.-F.O.O.D. he's a restaurant owner/cook, in U.T.O.P.I.A. he's a scientist, and in this episode, he's a doctor.
(He also could of been the camp counsellor in C.A.M.P., but theres no proof yet.)

Numbuh1 hates the doctor

Numbuhs 2, 3, and 5 do not appear in either episode.

B.R.E.A.K.U.P. features the second appearance of Ernest. He returns from operation M.A.T.A.D.O.R., and even mentions it.
