Want to learn about Dennis's daredevil granny?
Check out her rockin' living room to find out more!
What's the coolest thing?
It's pretty much a tie between that motorbike and that guitar - trust us, they're both as loud as each other!
What's the most valuable thing?
Gran's trophy cabinet! First Prize for the Dangerous Gran Award 2009? That's one of a kind, just like Gran.
What are those decorations?
A lovely picture of Gran's son (Dennis's dad) - looks like he was taken by surprise! She's also got a some awesome posters of the original daredevil Evil Knievel, and ageing rock star Alice Cooper - no, it's not a girl's name! Go ask your dad!
