On the job

I attended a Toastmasters meeting today, and one of the speakers gave a short, pun-filled list of all of the jobs he'd claimed to have had and lost. Here are those I can remember:

My first job was in an orange juice factory, but I got canned. I couldn't concentrate.

After that, I tried being a lumberjack, but I couldn't cut it. They gave me the axe.

So then for a time I worked as a muffler repairman. I quite because I was exhausted.

I made an attempt to work as a doctor. Unfortunately I didn't have the patients for it.

After a break, I found my way to being a fisherman, but had to give that up too as I didn't have any net income.
