Similar to being tom sawyered. Being suckered into doing something which you originally thought was fun, only to turn out that what you are doing is indeed not fun.
"Come on, lets go chasing tornadoes. It'll be fun."

"No the last time you fostered me into chasing tornadoes I ended up in a mexican prison with a guy giving me a dirty sanchez."
