Very often the direction one receives is, "Ok, give me three versions of that line". It is very important to move the emphasis around when you're doing multiple takes. A lot of times people just try and vary the melody while they use the same cadence and that usually isn't enough. So try moving the emphasis.
i.e. "it is better to give than receive" "It is better to give than receive" "It is better to give than receive". Variations of cadence combined with slight shifts in the melody and where you breathe will give you endless combinations that will make any booth director your friend.
