Ron loved to laugh so I think he would like this. Take a look at this rather candid shot of his 1974 Topps card, #270. The hatless man "behind" Ron is the legendary Leo Durocher, the Cubs manager from 1966-72. It's no secret that Leo and Ron were not the best of friends.
I know this is just a case of bad photography but it looks to me as though a small Leo is attempting to "relieve himself" on Ron's jersey.
