When I was a little kid (like maybe 7?) I used to, regularly, for months, take the head off the shower and use the pipe to force water up my pee hole into my bladder and then pee it back out as a massive pee.
I found it hilarious.
Nothing bad ever happened.
I found out in later life that (in case you guys were thinking of trying it
) that this is EXTREMELY DANGEROUS to the point where a terrible infection is likely, but you can even do life-threatening damage. It can also cause erectile dysfunction
.
Kids eh!
