There was a student that had a chance to learn the sport of skydiving.
After having been instructed by his teacher he jumped out and forgot how to release his shoot.
As he was falling rapidly towards earth, he suddenly saw a man shooting up towards him and as the man passed by, the student yelled! “Do you know how to operate a parachute?â€
The man passing by him answered NO! “But do you know anything about a gas heater?â€
