A shepherd asks his sheepdog how many sheep are in the field. The dog answers “40”.
“I thought we only had 36′, replied the farmer, puzzled.
“Ah yes, sorry.’ replied the dog.
“I rounded them up.”

Never argue with 90 degree angles: they’re always right.
Two people go into any empty house, yet a moment later three people come out.
A physics, a biologist and a mathematician were watching.
The physicist said “We have to assume there was an error in the measurement.”
“No”, said the biologist. “They must have reproduced.”
“I don’t know about that”, replied the mathematical, “But I do know one thing. If another person goes into the house now, it will be empty.”
