Wave Machine

Last week I went to the gym 4 times, but on Friday I decided to go for a swim instead of using the machines.  This was mainly due to me having no clean kit...  The one time I happen to fancy a swim, it's the day when 2/3 of the pool is taken over by fat women jumping up and down in the water.  I was initially annoyed as there was only 1 lane for 3 people swimming, but then the other two chaps left and it was just me, with 15 fat women jumping up and down in unison it makes for quite a tricky swim.  Who needs a wave machine?
