At the RC Primary School my kids attended a teacher friend heard the followig "prayers"
In the Hail Mary,"pray for us sinners now" became "pray for us Cinemas now"
The sign of the Cross started "In the Name of the Father put your hand on your tum"
In the Memorare,"And was left forsaken" became "And was left for Satan
I suppose it works better if you are Left-Footer(RC)
On a slightly different tack,a 50 something Lady we know sings at Christmas time "May all your Christmas Eggs be white" instead of "May all your Christmases be white". Nobody has the heart to tell her.
