Ok, I'll try to 'Canadianize' the "****-List"..
1) The Lincoln Log Eh! (It's big and it floats!)
2) The Phantom **** Eh! (You felt it come out, you heard it splash, but when you look, it's nowhere to be seen!)
3) The Peek-a-boo **** Eh! (Every time you strain, it peeks out, but when you stop straining to breath it hides back in!)
4) The Brain-hemorage through your nose **** Eh!(..and it's not called blushing!)
5) The Super snake Eh! (also known as the spiral ****!)
6) The Memorable **** Eh! (So strange, big or unique that you need a witness!)
7) The Popcorn **** Eh! (you know plop, plop no fizz oh what a relief it is!)
8) The Niagra **** Eh! (aka the liquid ****!)
9) The Kodak **** Eh! (similar to the Memorable **** but you grab a camera because no-one is around!)
10) The Air **** Eh! (It's when you spend a half hour on the bowl farting!)
11) The Oxigen Deprivation **** Eh! (It stinks so much you have trouble breathing!)
12) The TNT **** Eh! (The one that litterly blows out of you in a matter of seconds, often associated with the 'liquid ****'!)
13) The Alien **** Eh! (Often recognized by it's strange yellow/green color! Are babies aliens?)
14) The Drain Blocker Eh! (The one you have to chop up in order to get it to flush!)
15) The Sanctuary **** Eh! (It's when you don't actually **** but use the privacy of the bathroom to get away from it all!)
16) The 'Executive' **** Eh! (reserved for the 'person' in the office that always has a **** at the same time every day!)
17) The literary **** Eh! (Where you bring a book or newspaper and fill your brain while emptying your bowels!)
Another way to make a joke Canadian is to insert random polite words like 'please', 'sorry', 'thank you', etc!

We Canadians are known to be extremely polite!
Cheers!
