1. Barking mad
I stood up to the fierce "be-quiet-Dennis-it's-just-a-vacuum-cleaner" and barked it away. My house has felt strangely dirty ever since ...
2. Spaced out
Some people might think this is lame, but the manliest thing I've ever done was going on Space Mountain at Disneyland. I'm really scared of roller coasters!

3. Notable effort
I once stood up in front of my class and bellowed the opening bass solo of Tuba Mirum from Mozart's Requiem. I could practically feel the testosterone rushing into my vocal cords.

4. Road sense
I don't mean to brag, but once I didn't look both ways before crossing a road. (OK, I was in a hurry! Always remember to look both ways before you cross the road!)

5. Knight-ly thing to do
My friend sprained her ankle quite badly when we were out together. As she could hardly walk, I simply picked her up and carried her on my shoulders! I bet I looked like a knight in shining armour!

6. Hair-raising move
What defines a man is the beard. Last year, I didn't shave my beard for a whole month! It worked particularly well with my Movember moustache, too.

The manliest thing I've ever done was smack a cockroach with my (bunny) slippers.

8. In good hands
I once opened a jar of syrup with my bare hands, when neither my dad nor 20-year-old brother could!

9. Sporty types
Hanging out with the jocks in school is definitely the manliest thing I ever did. I always wanted to spend some time with them but was too shy. So I just manned up and approached them, and they let me hang out with them!

10. The fiery side of me
Once in kindergarten, we all got to dress up and pretend to be doctors or postmen. Even though I specifically told the teacher I wanted to be a policewoman, I ended up being a fireman and I tried very hard to walk around like one. That was the manliest moment of my life.
