Francesca marches up and down (she was marching to some music but the music is muted for copyright reasons) and while doing so, she receives multiple buckets of water.
As a new WAM model she gets a valuable lesson in keeping your mouth shut when having water thrown at you... but a few (silent) coughs, and she just keeps going... what a trooper.
When the song ends, she holds up signs saying she was glad it wasn't pies this time... and so obviously ends up receiving a pie sandwich!
Sorry Francesca... you'll also learn not to say things like that pretty soon!
