Porto Rican (Mason and Espinosa):

342. Una en un minuto, dos en un momento, y ninguna en un siglo. [↑]

[88] Cf. Popular Rhymes and Nursery Tales (Halliwell), 143:

10. What God never sees,

What the King seldom sees,

What we see every day,—

Read my riddle, I pray.

Irish Folk-lore Riddles:

(Gaelic) I sought for it and found it, ’twas easy its finding,

The thing that God never found and never can find.
