Fluid Substance Puns

I've been having some diarrhoea troubles lately, and after another long toilet visit I was delighted to tell her it was starting to get more substance, and becoming less fluid.

She simply replied: I'm glad you're getting your shit together.

Yes, she's still chuckling about it.

EDIT: Whoa, this blew up more than I expected! Thank you all :D I'll be sure to let her read the replies!
