The moment on the Grinchs' clock that indicates it's time to steal Christmas, and time to get mean.
The answer above is almost certainly the right one, but it is just possible that the questioner was asking about Greenwich mean time.
Many who don't speak the Queen's English believe that Greenwich is pronounced "green witch." Almost all Brits say it 'grennitch', but a few (including Her Majesty), opt for "grinnitch." New Zealanders, who long ago abandoned "maj-speak", go for 'grinnertch'. The 'er' in this is a very short schwa, and the result sounds amazingly like Grinch.
The Grinch was mean because he was bullied and hurt as a child.
his heart was so small
the song from the Grinch
Christmas time
His heart was "two sizes too small."
Because his heart was two sizes smaller than usual
Mean and green but mostly grouchy and selfish.
Yes, he sang "Your a Mean One Mr. Grinch." Basically Jim Carrey is the man!
The Grinch's heart was two sizes too small in the beginning; and three time too large at the end.
The only name that the Grinch is ever called is simply "The Grinch".
The Grinch if we're talking movies
his heart was two sizes too small
