These jokes were popular in my high school during the early 1970s.
A terrorist was ordered to blow up a bus. He burned his mouth on the exhaust pipe.
A three eyed, one-legged alien with no arms was waiting at the bus stop. The bus driver gave him the once over and said
"Aye aye aye, you look 'armless, hop on!"
This joke I first heard from an acting headmaster who regarded himself as a cool dude:
The sky god Thor got drunk and spent the night with a mortal human tart. When he awoke and saw who was next to him, he was ashamed for demeaning himself and was prepared to stand on his dignity. The tart awoke too.
"Good morning, Hunky Wunky", she said.
"Hunky Wunky?" thundered the sky god. "I am mighty Thor!"
"Tho am I" she replied, "but letth do it again."
