how about these...

...you run..and run.. and run...and your not being chased.

...the stationary bike is the most used piece of furniture in your living room.

...your mat shoes are the most comfortable pair of shoes you own.

... or you mention the word "singlet", and the girl next to you confuses it with "chicklet" and asks you for a piece of gum.

...not everyone has heard infamous 5 pound orange.

..when you talk about descibing mat burns they say "who is Matt Burns?"

..."funk" is something that grows on your skin

...you use "bactroban" and "loprox" more than you use your acne medicine

...basket-ball sounds like something you would make in home-ec class.
