If you're getting ready to eat and you've got the family gathered around and you want to bless the food then for the love of crackers just get on with it and BLESS THE DAMN FOOD!
I mean this isn't the time for praying for Grandpa or for thanking Jesus for dying on the cross or whatever else happens to come into your mind while the chicken is getting cold. There's definitely a time and a place for that but when everybody is hungry and the food is on the table that ain't it.
If it lasts more than 10 seconds you're doing it wrong. Just thank Him for the grub and get on with it already.
