Daniel Webster
Made bad puns. I dug around quickly, but wasn't able to find any. He did say of the vice presidency "I do not propose to be buried until I'm dead and in my coffin." As far as I know, he did not add "it would be a grave mistake."
Nevertheless, the vice presidency would not have been a dead end for Webster. He passed on William Henry Harrison, who kicked the bucket a month into the job. And then again with Zachary Taylor, who lasted less than two years. Oh well... you live, you learn.
