thanks for the dicklordish response!
(Was that the correct use of the word dicklordish?)
This particular comedian was guessing about people's backgrounds and based his comedy act on shitty assumptions in desperation to say something funny. Where I come from the saying "drawing at strings" implies conjecture on the part of he who is "drawing at strings". My apologies if I was not clear on the nature of his conjecture.

The phrase "drawing at strings" only exists in your head, pet.
Sorry about that.

That's great if you're in to using main-stream phrases.
I stopped using "clutching at straws" before it was cool to clutch at straws.

And started using something that makes no sense, instead.
Why not just substitute gobbledygook words and phrases for everything you say?
