During my senior clinical in the ER, I had to insert a foley into an 80+ year old man with an uncircumcised penis. I started to become nervous for some reason (I don’t know why because I have done it once already on an uncircumcised patient). I was trying to do the whole “one hand becomes non-sterile and the other stays sterile” bit but my being a righty couldn’t get the foreskin down with my left hand. For a few seconds there, it looked like I was doing something naughty and as my preceptor walks in, the patient goes “It’s better to use both hands!” I looked at my preceptor and we both tried REALLY hard not to burst out laughing.
