Here is one of my funny jokes

3 rc helicopter pilots at a fun fly where in the tiolets taking a piss, one nitro, one gasser, and one electric.

The nitro pilot finishes and walks over to the sink to wash his hands. He then proceeds to dry his hands very carefully. He uses paper towel after paper towel and ensures that every single spot of water on his hands is dried. Turning to the other two, he says, "We nitro pilots are extremely thorough."

The gasser pilot finishes his task at the urinal and he proceeds to wash his hands. He uses a single paper towel and makes sure that he dries his hands using every available portion of the paper towel. He turns and says, "We gasser pilots are not only trained to be extremely thorough but we are also extremely efficient."

The electric pilot finished and walks straight for the door, shouting over his shoulder: "We electric pilots don't piss all over our hands."
