It's stressful to have to do these, but it could be worse. I was once called on to give such a speech impromptu when the best man got lost for over an hour between the wedding site and the reception -- now there is some stress. I mostly made fun of the groom for being bald and paunchy compared to his hot wife. Everyone but him loved it, and I owed him one for putting me on the spot.
I'm in favor of liberalized immigration because of the effect it would have on restaurants. I'd let everybody in except the English.
