Some Following SA's I remember in this way.
SA 299 : Responsibility of Joint Auditors ( 99 same no. So they are joint).
SA 310 : Knowledge of Business ( If A=1, B, 2, C=3 then 31 is CA, & CA has the Knowledge of Business)
SA 505 : External Confirmations ( in 505 , No. 5 is placed at the extreme ends, therfore external Confirmations)
SA 550 : Related Party ( 5 5 both are same i.s relative of each other i.e related parties)
SA 570 : Going Concern ( The Word Going is of 5 Alphabets & Concern is of 7 alphabets)
SA 600, SA 610, SA 620 : At the Age of 60 a person becomes another auditor, at age of 61 internal auditor & at the age of 62 he becomes Expert.
