What are the things your dogs do that make you laugh?

This is a regular occurence in our house.  We have 3 dogs (2 Min Pins and a Min Pin mix) and 4 cats ("mutts").   The last cat we got, Mojo, I found/caught when he was a tiny kitten, and he's very shy.  But he's the only cat that actually grew up with the dogs.  The other cats don't mind the dogs but they don't *love* them. 
 
Anyway Mojo, within a couple of days of my bringing him home, developed uhmmmm a *special bond* with our littlest dog Echo.  I need a video of this.
 
I know it's a dominance thing, but it's still funny, well it's kind of gross too.  LOL
 
Echo and Mojo love each other.  They will do a little "dance" around each other then uhmmm Echo climbs on Mojo's back and humps on him.  The cat is a fixed male and the dog is a fixed female.  Then Echo nibbles on Mojo's neck, and Mojo rolls onto his back and grabs Echo's head.  Then sometimes Echo runs circles around the coffee table before humping on the cat again.  It's a game they play almost every night.  Mojo comes looking for Echo to play with.  If Echo's on the sofa next to me all I have to do is say "Echo!  There's Mojo!  Get Mojo!" and Echo flies off the sofa and goes and plays with Mojo. 
 
It's hilarious and disgusting at the same time.  I need to get a video of it and post it on YouTube.  Echo humps really frenetically on the cat's back (Mojo just acts like he's getting a great back rub, LOL), and rolls her eyes up in her head while she's humping, ohhhh anyway here are the photos I have of this.  I'd get a video but we never have the overhead light turned on in the room so it's be too dark to see what's going on.  I'll have to figure something out someday. 
 

 

My 1.5 yo lab, Emma is a whirlwind and everything she does is done at breakneck pace and speed.
 
Our pup, Aidan, 7 months, is the opposite. He is prefectly content to hang out on the couch for belly rubs. But he makes us laugh when he is REALLY happy to see you he will give licks and ear nibbles. Just the ear lobe...he gives a few little nips to.

I have a pic, so it will be easy to show. Shadow taught himself this one not long after we got him. Yes, he can throw the rope frisbee and catch it. But this trick is different. He will step one paw through the hole and and pick up the rope in his mouth and then walk 3-legged, carrying is roped paw.
 
 

 My son's chihuahua Ricco does some pretty funny things!  My son will take Riccos tennis ball with a bell in it and put it down his shorts. Then my son will squeeze the ball so Ricco will hear it.. and Ricco will run over to my son and start digging at his crotch trying to get his "ball" ..... and he will keep digging and digging..lol.. until you stop him!  []
He also had to go buy him a stuffed dog that looks exactly like our dog Anna..(cocker spitz mix) because Ricco has always been "in love" with Anna. Normally he tears up his stuffed animals by ripping out the eyes first so that they "cant look at him" while he is "killing " them... but his "anna" dog.. he LOVES and just licks and carries around with him!  []
