Boy, they sure are Irish!
Both Barbecue and Blowtorch are two sides of the same stereotype: Blowtorch is the one on the cartoon with standard Irish accent, the kind of heavy brogue often seen on cartoon Irishmen; Barbecue, meanwhile, comes from a family of Boston (or Bahstahn, if you prefer) firemen, and it doesn't get much more Irish than that.
You remember the scene in Futurama's "The Farnsworth Parabox" where the Universe A Professor and the Universe 1 Professor are taking turns adjusting the knob for the chandelier-mo-stat, to no net change? I imagine that's what you get when you put these two guys together: one starts fires, the other stops fires. Wonder if they get along in real life?
And in case you didn't recognize it, that's Joe Headquarters that's on fire behind them.
