Stupidly loud Audi R8s send crowds wild!

We have absolutely no idea what was going on, but while out for a drive with some friends in my R8 V10 with QuickSilver exhaust, an R8 V8 with Larini exhaust behind (with R8 GT bodykit), another R8 in matte green, a Boxster S and an SLS Roadster, we stumbled into this crazy crowd of rather drunk people we assume are students, at lunchtime too and all dressed up as animals and all sorts! It seems that some noisy supercars plus some very noisy students makes for a massive amount of craziness! Bonkers. Like
