If God did not exist, it would be necessary to invent him
If God had meant us to fly he would have given us wings
If I had to do the same again, I would my friend Fernando ( ABBA lyric )
If I said you had a beautiful body would you hold it against me?
If all the world were Jell-O, And whipped cream filled the sea, Then the only spoon from here to the moon Would have to belong to me ( Jell-O Gelatin Dessert advertising slogan )
If enough people would stop smoking and start drinking, we could get out of ashtrays and into vermouth ( Cinzano advertising slogan )
If man were meant to fly, God would have lowered the fares ( American Coach Lines advertising slogan )
