Don't know how I missed this thread, but I am a huge fan of sitting on balloons. But I am not so much into "riding". I might tease the balloon for a few seconds, but then my fat butt comes down and bang!
I knew that I needed to drop a few pounds when I got on a not-too-full Q24 a few weeks ago and popped the stupid thing almost instantly

Oh well... good motivation for me to get my act together before swimsuit season!
