Here’s a fun one:
In Act 2, Scene 8, Salarino tells Salanio about a Venetian ship that wrecked in the English Channel. Salanio’s responds with:
You were best to tell Antonio
what you hear—
Yet do not suddenly, for it may grieve him.”
It certainly will grieve him, because if it turns out to be one of his ships, he’ll forfeit his debt to Shylock. In OP, though, grieve is pronounced like grave, so we get a new pun there. You could say, colloquially, that the grief would kill him; but also, forfeiting to Shylock means paying with a pound of flesh, which more likely than not will kill him very literally.
