I am looking for a Fathers Day present for my dad. I am looking to get him something swimming pool related. He has a pool which he pretty much has gatherings there every weekend. Usually from 10-20 people over at a time. Mostly it is his friends(aged 30-40ish) and bring their kids(aged 3-10ish). I occasionally go over and bring a few friends(early 20s). Need something to appeal to this crowd. Nothing extravagant.
-100 dollarish range at most.
-Could be something for the kids or adults. Don't really care, just something that will get use occasionally.
-Could be something that is totally for laughs but nothing inappropriate for the kiddos. Don't hesitate to post it.
-We have 2 full fridges of beer at all times, so no need for suggestions on that front.
-Please provide link as to where to buy it.
