The phrase stinking thinking makes me think of SNL character Stuart Smalley:
"I'm good enough, I'm smart enough, and doggone it, people like me."
"That's just stinkin' thinkin!"
"You're should-ing all over yourself."
"Denial ain't just a river in Egypt!"
"I am a worthy human being."
"...and that's...okay."
"Trace it, face it, and erase it."
"I don't know what I'm doing. They're gonna cancel the show. I'm gonna die homeless and penniless and twenty pounds overweight and no one will ever love me."
"I'm in a shame spiral."
"You're only as sick as your secrets."
"Compare and despair."
"You need a checkup from the neckup."
"I am a human being, not a human doing."
