How do we know they're talking about the same Bill?

So 0 because Bill says he has no brothers.

I feel like this is a PQ maybe....

 

[Fierro]

I'm still insisting that it's 98.

 

[dogmeat]

Bill has 3 sisters

also, what are their pronouns?

 

[Luki]

I'm gonna say 6, because Xhuxhmaxhuxh needs to qualify.

 

[Sabrewulf238]

Bill has 3 sisters

also, what are their pronouns?

Oh I hate that I fell for that.

 

[esc87fan]

Woohoo, both of the newest members of the Century Club are through! Congrats Gary!

 

[ferret]

Correct answer:

Not one. He has three sisters who are doctors by profession.

​

What month has 28 days?

​

And we only have 2+2=4 spots left in the finals...

 

[Nicholas123]

12! plz be 12!!! All months have 28 days.

 

[Fierro]

All of them have 28 days at least.

The answer is 12

 

[Sabrewulf238]

Yeah I'm thinking it's 12 too.

 

[Karhu]

Only 1 month is able to have exactly 28 days (except on leap years). The answer is clearly 1

 

[esc87fan]

All of them! (12)

 

[Sabrewulf238]

Only 1 month is able to have exactly 28 days (except on leap years). The answer is clearly 1

It didn't ask which months has exactly 28 days though.

Sorry I know I'm raining on your parade.

 

[ferret]

Correct answer:

In each of the 12 months!

​

Two brothers won 100 pounds in a lottery. The older brother got twice as much as the younger brother
and plus 7 pounds more. How much did the younger brother get?

​

 

[HayashiM]

31 pounds ( (100 - 7) / 3 )

 

[Sabrewulf238]

No idea what the answer is but I was googling and I found this picture of two brothers who both won the lotto on the same day.

 

[ferret]

Correct answer:

31 pounds (69 at Sr.)

​

A man dies of old age on his 25th birthday. How is that possible?

​

 

[HayashiM]

Born 29th of Feb?

 

[Sabrewulf238]

He died at 100 and he was technically 25 because he only had a birthday on the 29th February which only happens during a leap year.

So the answer is 29.

Is this finally the leap year riddle?

 

[strajker]

Where's 9
