Gruntosaurus Rex 

taking a dinosaur-sized crap; would win the "shit of the year" contest; the kind of dump where you lose weight.

After not crapping for a week, I sat down and loaded up the bowl with a Gruntosaurus Rex.

Heavens to Grundo 

An expression of shock, or disbelief.
Like Heavens to Betsy! or Oh My God! but mainly said by Newton Gimmick on Teddy Ruxpin.
