It's stories like these that make me paranoid and check the oven when I turn it on just in case. If anyone has little kids, you know you will find all kinds of crap in places you never thought of. So always check to make sure some Lego design wasn't stored in the oven to hide it from little brother/sister.
Now, who hasn't used a spray can as a flame thrower? In college, I was trying to grill burgers but the charcoal wasn't going well at all. So made a flamethrower using lighter fluid and such. Not saying there was certain beverages involved, but there was. So needless to say my aim was off a bit. Lighter fluid on burgers...man you will be burping that up all night...
