A guy falls asleep on the beac...

A guy falls asleep on the beach for several hours and gets a horrible sunburn all over his body.

He goes to the hospital and is promptly admitted after being diagnosed with second degree burns on his legs.

He was starting to blister and in pain by the time the doctor arrived. To help, the doctor prescribed an IV with saline and electrolytes, asedative, and a Viagra pill every four hours.

The attending nurse was rather surprised by the prescription and asked, "What good will Viagra do him?"

The doctor replied, "It will keep the sheets off his legs."

The path of totality crossed the Atlantic, the Sahara Desert and East Africa. The moon’s shadow travelled at over 3,000 km per hour.
