I've only eaten Jerusalem artichoke once and later that evening I was praying for death as my ravaged trumpet put paid to the walls of Jericho.
Celeriac also gets me every time with the sort of seismic activity that sends even a seasoned Californian cowering in a doorway. It's no help when the foul pyroclastic flow catches them a moment later. If you make the toilet, it feels like you are shitting the Hindenburg. And it's on fire.
Lentils induce an aromatic bubbliness, a sort of deranged anal giggling, like your nethers have been possessed by a demonic presence and it can't help but reveal its foul schemes to anyone in the vicinity.
Mushy peas induce a more gentle blast-off, more ion-drive than hydrazine. Like hydrazine though, don't stand nearby, and unlike hydrazine, it's certainly not odorless.
