Both characters have had to overcome their physical limitations: one a dwarf, the other a baby. Both are possessed with cunning and high intelligence. Further still, neither are overly keen on their own family.
We're surprised it's taken this long for the internet to create a mashup of Game Of Thrones' Tyrion Lannister and Family Guy's very own Stewie Griffin.
Weirdly, even the animation seems to fit perfectly.
If these two characters were ever combined, we're pretty certain they'd take over the Earth and Westeros.
