"Buzz Off" joke

One day, two bees are buzzing around what's left of a rose bush.
"How's your summer been?" asks bee number one.
"Not too good," says bee two. "Lotta rain, lotta cold. There aren't
enough flowers, therefore not enough pollen."
The first bee has an idea. "Hey, why don't you go down to the corner and
hang a left? There's a bar mitzvah going on. Plenty of flowers and
fruit."
Bee two buzzes, "Thanks!" and takes off. An hour later, the bees bump into
each other again.
"How was the bar mitzvah?" asks the first bee.
"Great!" replies the second.
The first bee, however, notices a small circle on his friend's head, and
inquires, "What's that on your head?"
"A yarmulke," is the answer. "I didn't want them to think I was a Wasp."
