"They sort of jumped on my plate"

Grrr put on a few lbs...
Grrr had just returned from Hollywood. He and Gretta, once as you know A list actors, before retiring to become clas dinos, had gone back to visit old friends.....Bob and Grrr were on a morning walk..not a run today.
""Hey pal, ya got fat ;is that why ya gave up running?" asked Bob
"Ok, so I put on a few lbs Hollywood parties...not my fault!" replied an annoyed T Rex 
"Not your fault? They held a mauser to ya head to make ya stuff ya face or jumped onto ya plate?" Bor asked
"In point of fact, old ape, that is just what they did! Well almost."
"Someone held a mauser to your head?" asked Bob.
"No..they sort of jumped on my plate...." Replied Grrr
