Setting up the tribute (With humor)

I've known the groom for a number of years and of course there are plenty of things I could tell you about what he got up to in his younger days. However, at the bride's request I've been asked to keep things to a minimum... and only talk about his positive attributes.

What can I tell you about the groom? He’s a terrific guy. I couldn’t tell you all the things he’s done for me over the years – but he’s asked me to try.
