Funny Animal Christmas Puns

Hello, I would like to enlist the dads (or aspiring dads) of this sub. I have been tasked with getting jokes for Christmas crackers but I would like them to be themed. I need 3 jokes for each theam. The theams are as follows :

1. Some simple animal ones

2. Some computer jokes

3. Mum worthy jokes

4. Crochet /knitting ones

5. Really dirty and insulting ones

6. Fishing ones

7. Cheese and cows

8. General jokes (this person is easy going)

They can all be dirty except number 1 (they are a child) but number 5 must really insult and be dirty. They can not be too long but must be groan worthy but still funny.

Thank you for all your help.
