My first thoughts echoed that of the first two posters, so I'll offer this:
The least boring moments at the Hall were the non-Hall moments. When a speaker flubbed badly, "Thank you for sharing your tits with us, er, um, that is, TIPS with us, Sister Buxom," that sort of thing. The speaker tells a genuinely funny joke, a kid gives a particularly funny answer (often unintentional). The boring parts (99%) are the parts we're meant to hear. When a little something off the schedule occurs, that's when there's some fun.
