--- Tarmac and Spearmints ---

Both of these are pretty similar:

Tarmac

A blue piece of tarmac walked into a pub and ordered a beer. He then took it and sat down at the bar.

Then, a black piece of tarmac walked into the pub and ordered a beer. He also took it and sat down next to the other tarmac.

Suddenly, another piece of tarmac enters the pub and asks for a beer. The other two hide in the corner, cowering and avoiding him.

Later, when the third piece of tarmac had left, the barman asks the other two "Why did you cower away like that?"

"Because of him," replied one of them "He's a cyclepath!"

Hint: This sounds like psychopath

Spearmints

A polo walked into a pub and ordered a beer. He then took it and sat down at the bar.

Then, a tic-tac walked into the pub and ordered a beer. He also took it and sat down next to the other tarmac.

Suddenly, another mint enters the pub and asks for a beer. The other two hide in the corner, cowering and avoiding him.

Later, when the last mint had left, the barman asks the other two "Why did you cower away like that?"

"Because of him," replied one of them "He's menthol!"

Hint: Menthol sounds like mental
