4 and 9 are two recurring joke numbers in Sgt Frog Abridged and the meta-universe of TheMidnightFrogs. 4 has been in use as far back as SFA2 ("Quatro") with 9 following in SFA4, but they became recurring numbers between SFA4 and SFA6 after Yoshi and Thorn noticed that the numbers kept popping up in-series and in their private lives.
