I can tell you the lowlight of the wedding speeches that I have ever heard went as follows:
Bestman stands up ( he is a plumber)
looks over to the Groom (he is also a plumber)
" I knew Michael always took his work seriously, but I didn't know how seriously 'til he told me he was going to marry an old boiler like ________ ."
He was lucky to make it out of the venue with his life!
