Silly String Puns

Scientist #1: I think we should name them something funny like doodoo strings

Scientist #2: Yeah, i think that’s pretty silly, but i think they should be called something more Cillia

My dad and I were walking through a parking lot when I saw a piece of string hanging from the ceiling. Being silly, I told him "Hey watch out, there's a piece of string!"

So my dad, confused, asks "Why should I be careful of a piece of string?" and I answer "I don't know, maybe you're afraid of string"

His face lit up and he answered "I'm a frayed knot".

I give up.
