Our Father
In the Earth religion of Christianity, Our Father were words of worship spoken to God. 

Seamus, a holographic character from Fair Haven, had a habit of breaking the Fifth Commandment – "Honor your father and mother." He confronted  Mulligan (The Doctor) for "a bit of counsel," after having broke Fifth Commandment again. Mulligan's resolve for this was for Seamus to say ten Our Fathers and to call him in the morning. ()
