cherry slight disclaimer - I've been to mostly very normal lovely weddings in my life, so my idea of a totally bizarre wedding may be less bizarre to you...but here goes anyway, just a few points that stand out! I'm the groom's cousin, but don't see his (massive) family very often.
First weird thing was at the church (the service started at 12.30!), where the order of service said that "the address" was to be by the bride's Dad. But he did his father of the bride's speech instead...and it wasn't particularly sentimental or anything, he just held up a few of her more embarrassing belongings and made a bit of fun of her.
We then had 5 hours to kill until the reception! The invitation stated that at 7pm there would be speeches, followed by cutting the cake, followed by light finger buffet and dancing. At 7.15pm everyone was milling around aimlessly in the hotel reception, at which point the father of the groom came wandering past, all blase, wearing a dressing gown - having been in the steam room
We continued to mill until he returned, very red and sweating but suited up at about 7.30, and we were then ushered through to the reception venue. We all sat at tables......and sat. And waited. And waited. No food, no drink, no music, just....waiting.
At about 8.15 waiters started pouring a bit of sparkling wine into glasses, and then we waited some more. At about 8.30 the speeches started 
The speeches were a bit ridiculous. No microphones, so could hardly hear a thing. The father of the bride said he might pick up where he left off in the church, but changed his mind and instead read some excerpts from books entitled "what husbands should not do" and "what wives should not do" or something like that. But he'd start each excerpt, then "realise" it was too rude, and trail off. And that was his speech
. Not a word about his lovely, beautiful daughter!! The groom had his speech on his laptop screen on the table - he just stood looking down at it, talking at it. Didn't catch a word of what he said (and my table was pretty close!). The best man spoke incredibly quickly and quietly. The only words I caught were "bin bag" and "flipflops".
THEN the DJ started. What a legend. He must've been in his 50s, played total dancefloor clearers all evening, and every now and then he'd randomly announce what time it was!!
I gave up at about 10pm and waddled to bed.
Wow that's quite long - hope it's worth a read!
