In this world it rains on the Just and the Unjust alike, but the Unjust have the Just's umbrellas

He looked like the sort of person who would tell you that he did not have an umbrella to lend you when he actually had several and simply wanted to see you get soaked.

It never rains on the pass parade. It may rain before. It may rain after, but it never rains on the Pass Parade, but it is a time to for a moment, put aside all that has happened and just celebrate.

The rain it raineth on the just And also on the unjust fella, But chiefly on the just, because The unjust steals the just's umbrella

Don't pray when it rains if you don't pray when the sun shines.

And when it rains on your parade, look up rather than down. Without the rain, there would be no rainbow.
