Funny Camp Puns

I work at a summer camp where my ongoing joke is instead of doing activities we are going to real, eat vegetables and do math. one kid did not find it funny and asked why:

kid: why do we have to do math? Do you ever use it during summer?

me: sum times.

I repeated it with emphasis on both words for a bout a minute or so until his eyes rolled.

I went over to my friend's house, as we're planning a weekend of camping in funny clothes, and there’s still some sewing left to do.

Her: Do you know if your mom knows how to sew gussets? Me: I can only GUSSET my mom's skills with sewing.

I laughed, her husband laughed. She and the children groaned.
