Our patient laughed. I was reminded of 'Curious George Goes to the Hospital', where George makes a horrible mess but manages to raise the spirits of sad Betsy.
The EMT-I made me trade places with him... He said he needed to make a radio call, but I think he just didn't want to be sitting on the wet spot under the dripping ceiling. It did gave me the opportunity to practice taking vitals in a moving, noisy truck, and I was already wet, so I guess it was okay.
After we turned over care to the emergency department, the (still wet) EMT-I took me aside and told me sternly, "No one finds out about the heat pack. No one." He had that look in his eye.
