Nobody wants to take the first bite of a shit sandwich
Instinctively that would seem to be true and self evident. But I got thinking about it a bit more.
While the statement is true, there is a more general form which is also true. Actually nobody wants to take any bite of a shit sandwich.
But is the statement really true? Consider this situation. It's between you and some other guy. There's a shit sandwich. One person takes the first bite. The other person has to eat the rest. Well in that case suddenly that first bite doesn't seem so bad.
